A rigid body is in pure rotation, that is, undergoing fixed axis rotation. Then which of the following statement(s) are true?

Dynamics of rotational Motion about fixed axis of rotation

Equation and Fixed Axis Rotation

S_(1) : Net torque on a system due to all internal force about any point is zero. S_(2) : For rigid body undergoing fixed axis rotation, the direction of its angular acceleration and angular velocity S_(3) : if net torque on a rigid body about its centre of mass is zero, the angular speed of the rigid body is always zero. S_(4) : For a rigid body undergoing fixed axis rotation abouts its centre of mass, then net torque on rigid body about any point is same.

A rigid body is rotating about fix axis. P and Q are its particles. Which of the following physical quantity is same for P and Q?

Basics of Rotational motion & Kinematics of fixed axis of rotation

A rigid body is rotating about an axis. To stop the rotation, we have to apply

A rigid body is rotating about a vertical axis at n rotations per minute, If the axis slowly becomes horizontal in t seconds and the body keeps on rotating at n rotations per minute then the torque acting on the body will be, if the moment of inertia of the body about axis of rotation is I.

For a particle of a rotating rigid body, v = r omega , which of the following are correct ?
