Forces and Motion

Momentum.

Anything that moves has momentum (see also kinetic energy).
The amount of momentum which an object has depends on
how fast it is moving (its velocity) and on the mass of the object.

Momentum = mass x velocity.

The equation is written as
p = m x v
where p = momentum
m = mass and v = velocity.

This equation is important!

The units of momentum are kgm/s, called "kilogram metres per second".
