Front

What is the formula for momentum?

Back

p = mv (momentum = mass × velocity)

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time.

Front

What is the relationship between impulse and force?

Back

Impulse is equal to the average force multiplied by the time duration over which the force acts.
