In physics, velocity is speed in a given direction. Speed describes only how fast an object is moving, whereas velocity gives both the speed and direction of the object's motion.^[1] To have a constant velocity, an object must have a constant speed and motion in a constant direction. Constant direction typically constrains the object to motion in a straight path. A car moving at a constant 20 kilometers per hour in a circular path does not have a constant velocity. The rate of change in velocity is acceleration. Velocity is a vector physical quantity; both magnitude and direction are required to define it. The scalar absolute value (magnitude) of velocity is speed, a quantity that is measured in metres per second (m/s or ms⁻¹) when using the SI (metric) system.

For example, "5 metres per second" is a scalar and not a vector, whereas "5 metres per second east" is a vector. The average velocity v of an object moving through a displacement Failed to parse (Missing texvc executable; please see math/README to configure.): ( \Delta \mathbf{d})

during a time interval Failed to parse (Missing texvc executable; please see math/README to configure.): ( \Delta t)
is described by the formula:

Failed to parse (Missing texvc executable; please see math/README to configure.): \mathbf{\bar{v}} = \frac{\Delta \mathbf{d}}{\Delta t}.

the error analysis will look like this

Failed to parse (Missing texvc executable; please see math/README to configure.): \frac{\Delta \mathbf{\bar{v}}}{\bar{v}} = \frac{\Delta (\Delta \mathbf{d})}{\Delta d} + \frac{\Delta (\Delta\mathbf{t})}{ \Delta t}.

The rate of change of velocity (in m/s) as a function of time (in s) is acceleration (in m/s²) – how an object's speed or direction of travel changes over time, and how it is changing at a particular point in time.

Equation of motion[link]

The velocity vector v of an object that has positions x(t) at time t and xFailed to parse (Missing texvc executable; please see math/README to configure.): (t + \Delta t)

at time Failed to parse (Missing texvc executable; please see math/README to configure.): t + \Delta t

, can be computed as the derivative of position:

Failed to parse (Missing texvc executable; please see math/README to configure.): \mathbf{v} = \lim_{\Delta t \to 0}{{\mathbf{x}(t+\Delta t)-\mathbf{x}(t)} \over \Delta t}={\mathrm{d}\mathbf{x} \over \mathrm{d}t}.

Average velocity magnitudes are always smaller than or equal to average speed of a given particle. Instantaneous velocity is always tangential to trajectory. Slope of tangent of position or displacement time graph is instantaneous velocity and its slope of chord is average velocity.

The equation for an object's velocity can be obtained mathematically by evaluating the integral of the equation for its acceleration beginning from some initial period time Failed to parse (Missing texvc executable; please see math/README to configure.): t_0

to some point in time later Failed to parse (Missing texvc executable; please see math/README to configure.): t_n

.

The final velocity v of an object which starts with velocity u and then accelerates at constant acceleration a for a period of time Failed to parse (Missing texvc executable; please see math/README to configure.): \Delta t

is:

Failed to parse (Missing texvc executable; please see math/README to configure.): \mathbf{v} = \mathbf{u} + \mathbf{a} \Delta t.

The average velocity of an object undergoing constant acceleration is Failed to parse (Missing texvc executable; please see math/README to configure.): \tfrac {(\mathbf{u} + \mathbf{v})}{2} , where u is the initial velocity and v is the final velocity. To find the position, x, of such an accelerating object during a time interval, Failed to parse (Missing texvc executable; please see math/README to configure.): \Delta t , then:

Failed to parse (Missing texvc executable; please see math/README to configure.): \Delta \mathbf{x} = \frac {( \mathbf{u} + \mathbf{v} )}{2}\Delta t.

When only the object's initial velocity is known, the expression,

Failed to parse (Missing texvc executable; please see math/README to configure.): \Delta \mathbf{x} = \mathbf{u} \Delta t + \frac{1}{2}\mathbf{a} \Delta t^2,

can be used.

This can be expanded to give the position at any time t in the following way:

Failed to parse (Missing texvc executable; please see math/README to configure.): \mathbf{x}(t) = \mathbf{x}(0) + \Delta \mathbf{x} = \mathbf{x}(0) + \mathbf{u} \Delta t + \frac{1}{2}\mathbf{a} \Delta t^2,

These basic equations for final velocity and position can be combined to form an equation that is independent of time, also known as Torricelli's equation:

Failed to parse (Missing texvc executable; please see math/README to configure.): v^2 = u^2 + 2a\Delta x.\,

The above equations are valid for both Newtonian mechanics and special relativity. Where Newtonian mechanics and special relativity differ is in how different observers would describe the same situation. In particular, in Newtonian mechanics, all observers agree on the value of t and the transformation rules for position create a situation in which all non-accelerating observers would describe the acceleration of an object with the same values. Neither is true for special relativity. In other words only relative velocity can be calculated.

In Newtonian mechanics, the kinetic energy (energy of motion), Failed to parse (Missing texvc executable; please see math/README to configure.): E_K , of a moving object is linear with both its mass and the square of its velocity:

Failed to parse (Missing texvc executable; please see math/README to configure.): E_{K} = \begin{matrix} \frac{1}{2} \end{matrix} mv^2.

The kinetic energy is a scalar quantity.

Escape velocity is the minimum velocity a body must have in order to escape from the gravitational field of the earth. To escape from the Earth's gravitational field an object must have greater kinetic energy than its gravitational potential energy. The value of the escape velocity from the Earth's surface is approximately 11100 m/s.

Relative velocity[link]

Relative velocity is a measurement of velocity between two objects as determined in a single coordinate system. Relative velocity is fundamental in both classical and modern physics, since many systems in physics deal with the relative motion of two or more particles. In Newtonian mechanics, the relative velocity is independent of the chosen inertial reference frame. This is not the case anymore with special relativity in which velocities depend on the choice of reference frame.

If an object A is moving with velocity vector v and an object B with velocity vector w, then the velocity of object A relative to object B is defined as the difference of the two velocity vectors:

Failed to parse (Missing texvc executable; please see math/README to configure.): \mathbf{v}_{A\text{ relative to }B} = \mathbf{v} - \mathbf{w}

Similarly the relative velocity of object B moving with velocity w, relative to object A moving with velocity v is:

Failed to parse (Missing texvc executable; please see math/README to configure.): \mathbf{v}_{B\text{ relative to }A} = \mathbf{w} - \mathbf{v}

Usually the inertial frame is chosen in which the latter of the two mentioned objects is in rest.

Scalar velocities[link]

In the one dimensional case,^[2] the velocities are scalars and the equation is either:

Failed to parse (Missing texvc executable; please see math/README to configure.): \, v_{rel} = v - (-w)

, if the two objects are moving in opposite directions, or:

Failed to parse (Missing texvc executable; please see math/README to configure.): \, v_{rel} = v -(+w)

, if the two objects are moving in the same direction.

Polar coordinates[link]

In polar coordinates, a two-dimensional velocity is described by a radial velocity, defined as the component of velocity away from or toward the origin (also known as velocity made good), and an angular velocity, which is the rate of rotation about the origin (with positive quantities representing counter-clockwise rotation and negative quantities representing clockwise rotation, in a right-handed coordinate system).

The radial and angular velocities can be derived from the Cartesian velocity and displacement vectors by decomposing the velocity vector into radial and transverse components. The transverse velocity is the component of velocity along a circle centered at the origin.

Failed to parse (Missing texvc executable; please see math/README to configure.): \mathbf{v}=\mathbf{v}_T+\mathbf{v}_R

where

Failed to parse (Missing texvc executable; please see math/README to configure.): \mathbf{v}_T

is the transverse velocity

Failed to parse (Missing texvc executable; please see math/README to configure.): \mathbf{v}_R

is the radial velocity.

The magnitude of the radial velocity is the dot product of the velocity vector and the unit vector in the direction of the displacement.

Failed to parse (Missing texvc executable; please see math/README to configure.): v_R=\frac{\mathbf{v} \cdot \mathbf{r}}{\left|\mathbf{r}\right|}

where

Failed to parse (Missing texvc executable; please see math/README to configure.): \mathbf{r}

is displacement.

The magnitude of the transverse velocity is that of the cross product of the unit vector in the direction of the displacement and the velocity vector. It is also the product of the angular speed Failed to parse (Missing texvc executable; please see math/README to configure.): \omega

and the magnitude of the displacement.

Failed to parse (Missing texvc executable; please see math/README to configure.): v_T=\frac{|\mathbf{r}\times\mathbf{v}|}{|\mathbf{r}|}=\omega|\mathbf{r}|

such that

Failed to parse (Missing texvc executable; please see math/README to configure.): \omega=\frac{|\mathbf{r}\times\mathbf{v}|}{|\mathbf{r}|^2}.

Angular momentum in scalar form is the mass times the distance to the origin times the transverse velocity, or equivalently, the mass times the distance squared times the angular speed. The sign convention for angular momentum is the same as that for angular velocity.

Failed to parse (Missing texvc executable; please see math/README to configure.): L=mrv_T=mr^2\omega\,

where

Failed to parse (Missing texvc executable; please see math/README to configure.): m\,

is mass

Failed to parse (Missing texvc executable; please see math/README to configure.): r=\|\mathbf{r}\|.

The expression Failed to parse (Missing texvc executable; please see math/README to configure.): mr^2

is known as moment of inertia.

If forces are in the radial direction only with an inverse square dependence, as in the case of a gravitational orbit, angular momentum is constant, and transverse speed is inversely proportional to the distance, angular speed is inversely proportional to the distance squared, and the rate at which area is swept out is constant. These relations are known as Kepler's laws of planetary motion.

Marty Beller is the drummer for They Might Be Giants. He has two solo albums. He also wrote and sang songs from TMBG's albums, Here Come the ABCs: "Alphabet Lost And Found", Here Come the 123s: "High Five!" and Here Comes Science: "Speed and Velocity".

Beller became the full time drummer for the band in early 2004, breaking the "full house" that the band had before of two Johns and three Dans, after Dan Hickey's departure.

During the 2004 Spine Tour and the 2005 tour, John Flansburgh often introduced him as "the Next President of the United States of America, Mr. Marty Beller!"

On TMBG's 2011 album Album Raises New and Troubling Questions, the fourth song is "Marty Beller Mask" which suggests that TMBG's drummer is actually Whitney Houston wearing a mask of Beller. On the news of Houston's death, TMBG announced that they were retiring the song from public performance. ^[1]

Beller is married and has two children.

He is also currently the drummer for Jonathan Coulton's new band.

Johnny Marr (born John Martin Maher; 31 October 1963) is an English musician and songwriter. Marr rose to fame in the 1980s as the guitarist in The Smiths, with whom he formed a prolific songwriting partnership with Morrissey. Marr has been a member of Electronic, The The, and Modest Mouse. In 2008, he joined The Cribs after touring with them on 2008's NME Awards Tour, a group in which he would remain until 2011.

Marr's jangly Rickenbacker guitar-playing in The Smiths proved to be popular among other musicians and has influenced many guitarists that followed particularly in the Britpop era.

Marr was voted the fourth best guitarist of the last 30 years in a poll conducted by the BBC in 2010.^[1]

Childhood and personal life[link]

Marr was born in Ardwick, Manchester, the son of Irish immigrants.^[2] His parents came from Athy in County Kildare. In 1975^[3] he attended the Roman Catholic St Augustine's Grammar School, which in 1977^[4] merged with other schools to form a comprehensive school, St John Plessington High School. Marr had aspirations to be a professional football player, and was approached by Nottingham Forest and had trials with Manchester City (which he supports). In an interview with FourFourTwo magazine, Marr said "I was good enough for City, but they didn't follow up because I was probably the only player out there wearing eyeliner."^{[citation needed]} He currently resides in Manchester with his wife Angie and their children, daughter Sonny and son Nile. Johnny is an honorary board member of Rock For Kids. He is also teetotal and vegan, and runs regularly.

The Smiths[link]

The Smiths were formed in early 1982 by Marr and fellow Manchester resident Steven Patrick Morrissey (he had not yet abandoned his first and middle name), an unemployed writer. Marr's jangly Rickenbacker and Fender Telecaster guitar playing became synonymous with the Smiths' sound. Marr's friend Andy Rourke joined as bass player and Mike Joyce was recruited as drummer. Signing to indie label Rough Trade Records, they released their first single, "Hand in Glove", on 13 May 1983.

By February 1984, The Smiths fanbase was sufficiently large to launch the band's long-awaited eponymous debut album to number two in the UK chart. Early in 1985 the band released their second album, Meat Is Murder. This was more strident and political than its predecessor, and it was the band's only album (barring compilations) to reach number one in the UK charts. During 1985 the band completed lengthy tours of the UK and the US while recording the next studio record, The Queen Is Dead. In 1989 Spin magazine rated The Queen Is Dead as number one of "The Greatest Albums Ever Made". Spin was not alone in this designation—numerous periodicals rank The Smiths and their albums, especially 'The Queen Is Dead', high on their best ever lists. NME, for example, has dubbed the Smiths the most important rock band of all time.^{[citation needed]}

However, all was not well within the group. A legal dispute with Rough Trade had delayed the album by almost seven months (it had been completed in November 1985), and Marr was beginning to feel the stress of the band's exhausting touring and recording schedule. He later told NME, "'Worse for wear' wasn't the half of it: I was extremely ill. By the time the tour actually finished it was all getting a little bit... dangerous. I was just drinking more than I could handle."^[5] Meanwhile, Rourke was fired from the band in early 1986 due to his use of heroin (though he was reinstated in short order). In early 1987 the single "Shoplifters of the World Unite" was released to chart success, as well as mild controversy and concern from parents.^{[citation needed]}

Despite their continued success, personal differences within the band – including the increasingly strained relationship between Morrissey and Marr—saw them on the verge of splitting. In August 1987, Marr left the group, and auditions to find a replacement for him proved fruitless. By the time Strangeways, Here We Come (named after Strangeways Prison, Manchester) was released in September, the band had split up. The breakdown in the relationship has been primarily attributed to Morrissey's becoming annoyed by Marr's work with other artists and Marr's growing frustration with Morrissey's musical inflexibility.

Referring to the songs recorded in the band's last session together (B-sides for the "Girlfriend in a Coma" single, which preceded the album's release), Marr said "I wrote 'I Keep Mine Hidden', but 'Work Is a Four-Letter Word' I hated. That was the last straw, really. I didn't form a group to perform Cilla Black songs."^[6] In 1989, in an interview with young fan Tim Samuels (who later became a BBC journalist) Morrissey said that the lack of a managerial figure and business problems were to blame for the band's eventual split.^[7]

In 1996, Smiths' drummer Mike Joyce took Morrissey and Marr to court, claiming that he had not received his fair share of recording and performance royalties. Morrissey and Marr had claimed the lion's share of The Smiths' recording and performance royalties and allowed ten percent each to Joyce and Rourke. Composition royalties were not an issue, as Rourke and Joyce had never been credited as composers for the band. Morrissey and Marr claimed that the other two members of the band had always agreed to that split of the royalties, but the court found in favour of Joyce and ordered that he be paid over £1 million in back pay and receive 25% thenceforth. As Smiths' royalties had been frozen for two years, Rourke settled for a smaller lump sum to pay off his debts and continued to receive 10%. Morrissey was described by the judge as "devious, truculent and unreliable".^[8]

Both Marr and Morrissey have repeatedly said in interviews that they will not reunite the band. In 2005, VH1 attempted to get the band back together on its Bands Reunited show but abandoned its attempt after the show's host, Aamer Haleem, failed to corner Morrissey before a show. In December 2005 it was announced that Johnny Marr and the Healers would play at Manchester v Cancer, a benefit show for cancer research being organised by Andy Rourke and his production company, Great Northern Productions.^[9] Rumours suggested that a Smiths reunion would occur at this concert but were dispelled by Johnny Marr on his website.^[10] What did eventuate was Rourke joining Marr onstage for the first time since the Smiths broke up, performing "How Soon Is Now?".

In an October 2007 interview on BBC Radio Five Live, Marr hinted at a potential reformation in the future, saying that "stranger things have happened so, you know, who knows?" Marr went on to say that "It's no biggy. Maybe we will in 18 or 32 years' time when we all need to for whatever reasons, but right now Morrissey is doing his thing and I'm doing mine, so that's the answer really." This was the first indication of a possible Smiths reunion from Marr, who previously had said that reforming the band would be a bad idea.^[11]

Marr's guitar playing "was a huge building block" for more Manchester bands that followed The Smiths. The Stone Roses guitarist John Squire has stated that Marr was a major influence.^[12] Oasis lead guitarist Noel Gallagher has called The Smiths an influence, especially Marr whom he described as a "fucking wizard", also stating that "he's unique, you can't play what he plays."^[13] He also stated that "when The Jam split, The Smiths started, and I totally went for them."^[12] Radiohead guitarist Ed O'Brien has acknowledged that he idolised The Smiths in the 1980s; the band pays homage to The Smiths in their song "Knives Out". After O'Brien played with Johnny Marr in New Zealand in 2001, he acknowledged that Marr was the reason he had picked up a guitar as a teenager.^{[citation needed]}

Post-Smiths[link]

The Pretenders, The The, Electronic (1987–1999)[link]

After Marr left the Smiths in August 1987, he was very briefly an official member of the Pretenders. In late 1987, he toured with the band and appeared on the single "Windows of the World" b/w "1969". He then left the Pretenders, and recorded and toured with The The from 1988 through 1994, recording two albums with the group. He simultaneously formed Electronic with New Order's Bernard Sumner. Electronic were intermittently active throughout the 1990s, releasing their final album in 1999.

Session work (1987–2002)[link]

In 1992 he recorded a cover version of Ennio Morricone's The Good, the Bad and the Ugly for the NME compilation Ruby Trax together with Billy Duffy. Fellow Manchester band Happy Mondays also once tried to court him to be a member of their band, which did not work out.^[14]

He has also worked as a session musician and writing collaborator for artists including Pet Shop Boys, Billy Bragg, Black Grape, Jane Birkin, Talking Heads, and Beck. Marr played guitar on several Pet Shop Boys songs; he continues to have guest appearances on their albums, with his most significant contribution on Release (2002). The only remix that Johnny Marr has ever done was for the Pet Shop Boys—it was a mix of his favourite track from their 1987 album, Actually, called "I Want to Wake Up," and was released as the b-side to 1993's "Can You Forgive Her?" He later worked as a guest musician on the Oasis album Heathen Chemistry. He also joined Oasis on stage at a gig in 2001, playing "Champagne Supernova" and "I Am the Walrus".

Johnny Marr and the Healers (2000–Present)[link]

In 2000 Johnny recruited drummer Zak Starkey (son of Ringo Starr), Cavewaves guitarist Lee Spencer and ex-Kula Shaker bassist Alonza Bevan for his new project Johnny Marr and the Healers. The band had taken two years to come together as Marr had wanted members to be chosen "by chemistry". Their debut album Boomslang was released in 2003, with all lyrics and lead vocals by Marr. A second album was originally scheduled for release in April 2005, and a short tour was expected soon after, but Marr has since stated that the band is on the "side burner" for the time being (Manchester Evening News, May 2007). Drummer Starkey is currently involved with the Who, and Bevan has regrouped with Kula Shaker. In 2011, Johnny began performing with the Healers again. The new Healers line up consists of James Doviak on guitar, Max James on bass and Andy Knowles on drums.

Seven Worlds Collide (2001–2009)[link]

In 2001, Marr performed two Smiths songs and music by others with a supergroup called 7 Worlds Collide consisting of members from Pearl Jam, Radiohead, Split Enz and others, assembled by Neil Finn of Split Enz and Crowded House in 2001. A second set of concerts took place in December 2008/January 2009, and an album of new studio material titled The Sun Came Out was released in August 2009 to raise money for Oxfam.

Modest Mouse (2006–2009)[link]

In addition to his work as a recording artist, Marr has worked as a record producer. In 2006, he began work with Modest Mouse's Isaac Brock on songs that eventually were featured on the band's 2007 release, We Were Dead Before the Ship Even Sank. The band subsequently announced that Marr was a fully fledged member, and the reformed line-up toured extensively throughout 2006–07.^[15] During 2008, when Modest Mouse opened for R.E.M. during their summer tour of the United States, Marr would come on stage during the encore of R.E.M.'s set, for "Fall on Me" and, toward the end of the tour, "Man on the Moon". Johnny Marr and R.E.M.'s guitarist Peter Buck have often been compared by alternative music fans as having a similar guitar style.^{[citation needed]}

While with Modest Mouse, Marr was named an Honorary Patron of the University Philosophical Society, Trinity College, Dublin.^{[citation needed]}

The new album reached number one on the American Billboard charts in late March 2007. For Marr this is the first time he has had a number one record in the US. The highest chart position before that was with Electronic, who made the Top 40 in the singles chart with "Getting Away With It".^[16]

In 2007 Marr was appointed as a Visiting Professor in Music at the University of Salford, where he delivered an inaugural lecture (on 4th November 2008), and a series of workshops and masterclasses to students on the BA (Hons) Popular Music and Recording programme.^[17]

The Cribs (2008–2011)[link]

Marr performs as part of the Cribs at Washington, D.C.'s 9:30 Club in 2010.

In January 2008, Marr was reported to have been contributing his skill and experience to a secret songwriting session with Wakefield indie group The Cribs. Sources revealed that they worked together for a week at Moolah Rouge recording studio in Stockport – a favourite haunt of Bolton's Badly Drawn Boy, Damon Gough and fellow northern indie heroes I Am Kloot – and had penned a number of new songs.^[18] He also played at the Glasgow Barrowlands, Manchester Academy, Oxford Academy, Bristol Carling Academy, Leeds University, Cardiff University and Brixton Carling Academy with the Cribs on the NME Awards Tour. On 23 February 2008, XFM reported that Marr was to become a full member of the Cribs. On 28 February 2008, he also played onstage with the Cribs at NME Big Gig at the O2. Marr also played along with the Cribs at the Reading & Leeds Festival 2008, singer Ryan Jarman introduced Johnny as the newest member of the band, "Johnny Jarman". In 2009 Marr recorded an album with the band titled Ignore the Ignorant, which was released on 7 September.^[19] On Soccer AM in 9 September he explained he met up with the Cribs' bass player in Portland and it has gone from strength to strength. He says the Cribs latest album, Ignore the Ignorant, which came out last year, is "as good as anything I've done".^[20]

On April 2011 it was confirmed that Marr would no longer be part of the band.^[21] Marr, who had been understood to officially leave the band in January, released a statement in which he affirmed that he would be working on solo material "over the next year or so."^[22]

Recent soundtrack and session work[link]

In the late 2007, Marr's daughter Sonny performed backing vocals on the track "Even a Child" on Crowded House's album Time on Earth, on which her father Johnny played guitars.

Marr played a large role in making the score for the 2010 science-fiction/drama film Inception, which was written and directed by Christopher Nolan. Using a 12-string-guitar, he produced repetitive, simple melancholic tones that became a character theme for the protagonist, played by Leonardo DiCaprio. "I kept coming up with this phrase ‘churned-up,'" Marr said, "You’ve got this character who all the way through the film has this underlying turmoil." Longtime composer Hans Zimmer penned soundtrack.^[23] On 13 July 2010, Marr performed with an orchestra for a live internet broadcast of the soundtrack.^{[citation needed]}

In 2011, Marr worked on the Nuevo Noir movie The Big Bang.
