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.

When a torque acting on a system is increased, then which óne of the following quantities will increase? (a) linear momentum (b) Angular momentum (c) force (d) Displacement

Which of the following is a fundamental quantity velocity, acceleration, angular momentum, distance

If the resultant external torque acting on a body is zero, then angular momentum of the body

Obtain an expression for torque acting on rotating body with constant angular acceleration.

If no external torque acts on a body, will its angular velocity be 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.

If no external torque acts on a body, will its angular velocity remain conserved ?

If no external torque acts on a body will its angular velocity remain conserved ?

If no external torque acts on a body will its angular velocity remain conserved?
