MediumWhat is rotational motion and an axis of rotation?
(N/A) Rotational motion is the motion of a body in which all its particles move in circular paths about a fixed line,known as the axis of rotation.
$1$. Rotational Motion: When a rigid body rotates about a fixed axis,every particle of the body moves in a circle whose center lies on the axis and whose radius is the perpendicular distance of the particle from the axis.
$2$. Axis of Rotation: The axis of rotation is a fixed straight line about which a rigid body rotates. All particles of the body perform circular motion around this line. For example,the Earth rotates about its own axis.
