In classical mechanics, linear momentum or translational momentum (pl. momenta; SI unit kg m/s, or equivalently, Newton second) is the product of the mass and velocity of an object. For example, a heavy truck moving rapidly has a large momentum—it takes a large or prolonged force to get the truck up to this speed, and it takes a large or prolonged force to bring it to a stop afterwards. If the truck were lighter, or moving more slowly, then it would have less momentum.
Like velocity, linear momentum is a vector quantity, possessing a direction as well as a magnitude:
where p is the three-dimensional vector stating the object's momentum in the three directions of three-dimensional space, v is the three-dimensional velocity vector giving the object's rate of movement in each direction, and m is the object's mass.
Linear momentum is also a conserved quantity, meaning that if a closed system is not affected by external forces, its total linear momentum cannot change.
In classical mechanics, conservation of linear momentum is implied by Newton's laws. It also holds in special relativity (with a modified formula) and, with appropriate definitions, a (generalized) linear momentum conservation law holds in electrodynamics, quantum mechanics, quantum field theory, and general relativity. It is ultimately an expression of one of the fundamental symmetries of space and time, that of translational symmetry.
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.
A music video or song video is a short film integrating a song and imagery, produced for promotional or artistic purposes. Modern music videos are primarily made and used as a marketing device intended to promote the sale of music recordings. There are also cases where songs are used in tie in marketing campaigns that allow them to become more than just a song. Tie ins and merchandising could be used in toys are marketing campaigns for food and other products. Although the origins of music videos date back to musical short films that first appeared in the 1920s, they came into prominence in the 1980s when MTV based their format around the medium. Prior to the 1980s, these works were described by various terms including "illustrated song", "filmed insert", "promotional (promo) film", "promotional clip", "promotional video", "song video", "song clip" or "film clip". Since the creation and increased popularity of YouTube, mainstream artists now promote new music videos by releasing trailers of short promos on the site for their upcoming song and music video. Consequentially, YouTube has been converted into a social media platform for celebrities and artists to market themselves to their fans and audiences.

The songs I wrote on my first EP were spontaneous, and I hadn’t really thought out a whole vision for my project. It was kind of a photograph of my musical inspirations at the time. People took notice and when I went back to write ...

049 - Momentum In this video Paul Andersen will first define momentum as the product of an objects mass and velocity. He will then demonstrate how a net force acting on an object will change the momentum in the direction of the force. Several problems will be included. Do you speak another language?

Have any doubts? Follow this link http://avanti.in/peerlearning/signup and ask the experts. It’s free. Class 9 Science - Force and Laws of Motion This session and the following sessions will focus on the term FORCE. We have seen till now that how a body behaves when it is already in motion. Now we come to a more basic study as to how that motion started in the first place. What was the thing that someone did to set that body in motion? How a fan starts when we press the switch, what makes it move suddenly from rest? We’ll be able to answer these question after we finish this chapter. We’ll learn 1. What is a Force? 2. What are balanced and unbalanced forces? 3. Why a moving object, with no force acting on it comes to rest in real life and what is that force? 4. What are the 3 laws of moti...

Momentum and its conservation during collisions is introduced. Kinetic energy can decrease or increase during collisions. When kinetic energy is conserved, we call it an elastic collision.

A explanation of how to calculate momentum in 2 dimensions.
(Aimee Mann)
Verse 1:
Oh, for the sake of momentum
I've allowed my fears to get larger than life
And it's brought me to my current agendum
Whereupon I deny fulfillment has yet to arrive
Chorus:
And I know life is getting shorter
I can't bring myself to set the scene
Even when it's approaching torture
I've got my routine
Verse 2:
Oh, for the sake of momentum
Even though I agree with that stuff about seizing the day
But I hate to think of effort expended
All those minutes and days and hours
I have frittered away.
Chorus
And I know life is getting shorter
I can't bring myself to set the scene
Even when it's approaching torture
I've got my routine
Bridge 1:
But I can't confront the doubts I have
I can't admit that maybe the past was bad
And so, for the sake of momentum
I'm condemning the future to death
So it can match the past.
Bridge 2:
when I can't confront the doubts I have
I can't admit that maybe the past was bad
And so, for the sake of momentum
I'm condemning the future to death
So it can match the past.
