Rotational motion is more complicated than linear motion, and only the motion of rigid bodies will be considered here. A rigid body is an object with a mass that holds a rigid shape, such as a phonograph turntable, in contrast to the sun, which is a ball of gas.
Rotational motion involves an object rotating about an axis. – Examples include a merry-go-round, the rotating earth, a spinning skater, a top, and a turning wheel.

⏩The type of motion in which a body rotates around an axis is called rotational motion.
⏩Just like in rectilinear motion, rotational motion possesses angular-displacement, velocity and acceleration.
⏩The displacement is in terms of value of angle traversed with a reference point where angle= 0.
⏩Just like momentum is conserved in linear motion, angular momentum is also conserved in case of rotational motion.
⏩The mass is replaced by moment of inertia. Similar to force, it is torque which can change rotational motion.
