Impulse

What is Impulse?

Impulse is defined as force multiplied by the time for which the force acts, and it is equal to the change in momentum produced. Impulse equals F times delta t equals delta of m v, and it is measured in newton seconds, which are equivalent to kilogram metres per second.

This definition is part of the Motion, Forces and Energy chapter in Cambridge O Level Physics.
