Question

. An object of mass 5.0 kg is acted by a torque with a magnitude of 30 N⋅m for 2.5 seconds. During this time interval, the change in its angular momentum is

Definition Definition Product of the moment of inertia and angular velocity of the rotating body: (L) = Iω Angular momentum is a vector quantity, and it has both magnitude and direction. The magnitude of angular momentum is represented by the length of the vector, and the direction is the same as the direction of angular velocity.
