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.
Morgan Freeman (born June 1, 1937) is an American actor and narrator. Freeman won an Academy Award in 2005 for Best Supporting Actor with Million Dollar Baby (2004), and he has received Oscar nominations for his performances in Street Smart (1987), Driving Miss Daisy (1989), The Shawshank Redemption (1994) and Invictus (2009). He has also won a Golden Globe Award and a Screen Actors Guild Award. Freeman has appeared in many other box office hits, including Glory (1989), Robin Hood: Prince of Thieves (1991), Seven (1995), Deep Impact (1998), The Sum of All Fears (2002), Bruce Almighty (2003), The Dark Knight Trilogy, The Lego Movie (2014), and Lucy (2014). He is known for his distinctively smooth, deep voice. He got his break as part of the cast of the 1970s children's program The Electric Company. Morgan Freeman is ranked as the 4th highest box office star with over $4.316 billion total box office gross, an average of $74.4 million per film.
Morgan Freeman was born in Memphis, Tennessee, on June 1, 1937. He is the son of Mayme Edna (née Revere; 1912–2000), a teacher, and Morgan Porterfield Freeman, a barber who died on April 27, 1961, from cirrhosis. He has three older siblings. According to a DNA analysis, some of his ancestors were from Niger. Freeman was sent as an infant to his paternal grandmother in Charleston, Mississippi. He moved frequently during his childhood, living in Greenwood, Mississippi; Gary, Indiana; and finally Chicago, Illinois.

Momentum are a bunch of sinister, Machiavellian, far left extremists who invented internet trolling and want to nationalise your mum. Or so you might think if you read some of the press coverage about them. The grass-roots movement formed following Jeremy Corbyn's sweeping victory in the Labour leadership contest. I wanted to find out it the media portrayal of Momentum even comes close to reality.

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?

BBC Sunday Politics piece of the influence of the left and momentum with in the Labour party.
This video is about Planetshakers - Momentum - (with lyrics) (2016). I don't own any rights, for entertainment and worship purposes only.
Momentum national organiser James Schneider told Sky News the group had no intention of deselecting MPs. "This is a Labour movement that is trying to make the Labour Party more participatory, more democratic and more campaigning. It's a group of people who are inspired by Jeremy Corbyn."

(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.
