The impulse of a force is the product of the force and the time interval during which it acts. It represents the change of linear momentum.

  • The units of impulse are the same as those of momentum
  • Impulse represents the vector change in linear momentum

Impulse-momentum theorem

The change in momentum of a particle during a time interval is equal to the impulse of the net force acting on the particle during that interval.

Angular Impulse

The change in Angular Momentum is called angular impulse.
