Principle of angular impulse and momentum?

The principle of angular impulse and momentum states that the change in angular momentum of a system is equal to the angular impulse applied to it. Mathematically, this is expressed as ( \Delta L = \tau \Delta t ), where ( \Delta L ) is the change in angular momentum, ( \tau ) is the net torque acting on the system, and ( \Delta t ) is the time interval over which the torque is applied. This principle is crucial in analyzing rotational motion and helps in understanding how forces and torques influence the rotational dynamics of objects. It applies to both rigid bodies and systems of particles.
