Rotational motion occurs when an object moves around a fixed axis of rotation. The cause of rotational motion is a net torque acting on the object. Torque is a force that causes an object to rotate around an axis. The greater the net torque, the greater the angular acceleration of the object.

The outcome of rotational motion is that the object will rotate around the axis of rotation with a certain angular velocity. Angular velocity is the rate at which an object rotates around an axis. The greater the angular velocity, the faster the object is rotating.

Rotational motion is a common type of motion in the world around us. Examples of rotational motion include the motion of a fan, the motion of a wheel, and the motion of the Earth around its axis.
