The greater the mass of an object and the greater its velocity, the more momentum it has.

1 of 5

How do you calculate momentum?

Momentum (kg m/s) = Mass (kg) X Velocity (m/s)

2 of 5

How do forces change momentum?

A larger force means a faster change in momentum.

3 of 5

How do you calculate a force acting on a momentum?

Force acting (N) = Change in momentum (kg m/s) / Time taken for change to happen (s)

4 of 5

When is momentum used?

In car collisions, cars are deigned to slow people down over a longer time when they have a crash so the force is lessened e.g. seatbelts stretch to lessen the impact.
