Question

The rotational kinetic energy of a body is
e. In the absence of external torque

Answer 1

Answer:

Rotational Dynamics; Torque and Moment of Inertia. • Rotational Kinetic Energy. • Angular ... Every point on a rotating body has an angular .... In the absence of an external torque,.

Answer 2

Hey dude.....

The rotational kinetic energy of a body is e in the absence of external torque if mass of the body is halved and radius of gyration doubled then its rotatioanl kinetic energy will be. A body rolls without slipping. The radius of gyration of the body about an axis passing through its centre of mass is K.
