CONCEPT:

  • Angular momentum (L): The angular momentum of a rigid body is defined as the product of the moment of inertia and the angular velocity.
  • Net torque is directly proportional to the angular momentum, we get
     , t net is net torque applied to the body.


EXPLANATION:

  • Net torque is directly proportional to the angular moment, so when angular momentum is increasing net torque is also increasing.
