Momentum
The momentum of a moving object
 is found by multiplying its mass by
Its velocity. This makes the unit of
momentum Kgm/s. (Kilograms x
Metres per second)    Play the animations
In a collision, momentum is conserved. Momentum before the collision is the same as momentum after the collision. The first animation Shows two balls of the same mass colliding. In this collision the first Ball is half the mass of the second. In this collision both balls stick together and move off together
