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

Explosion situation
If two objects are held together under
tension and are not moving their
momentum is zero. When they are
released they move off in opposite
directions. Each one now has momentum
(Mass x velocity). The momentums of
each are equal but in opposite directions.
If we know the mass of each we can work
out the velocity of each
mass x velocity = mass x velocity
