When same torque acts on two rotating rigid bodies to stop them, which have same angular momentum,

Torque acting on a rotating body

Explain the torque acting on a rigid body.

Only rotating bodies can have angular momentum.

Only rotating bodies can have angular momentum.

When torque acting on a rotating body is zero, then which of the following remains constant?

(A) : When there is no external torque moment of inertia of a rotating body changes, its angular momentum remain conserved, but its kinetic energy changes. (R ) : Angular momentum does not depend upon moment of inertia of the body.

A torque of 50 Nm acts on a rotating body for 5 s. Its angular momentum

The angular momentum of a rigid body is

When there is no external torque acting on a rotating body, which of the following quantities can change ? (i) Angular acceleration (ii) Angular momentum (iii) Angular speed.
