Question

Define circular of a particle and rotational motion of a rigid body.​

Answer 1

Answer:

Circular motion is the motion of a body around a fixed point where the point lies outside the body.In rotational motion the point lies inside the rotating body. Circular motion is the cause of centripetal force while rotational motion is due to torque acting on the body.

Each part of a rigid body under pure rotational motion describes a circular motion about a fixed axis. In pure rotational motion, the constituent particles of a rigid body rotate about a fixed axis in a circular trajectory. ... Clearly, rotation of a rigid body comprises of circular motion of individual particles.
