Is circular motion and angular motion the same????
No. A particle cannot have angular motion. It can have circular motion. A body can have circular motion as well as angular motion. Angular motion is also called rotational motion. Circular motion is a translatory motion. A body can have either translatory or rotatory motion or a mixture of both. If a line joining any two particles of a body moves parallel to itself, the body has pure translatory motion. If the centres of circular motion of all particles of a body lie on a stationary axis, the body has pure rotational motion. If the axis of rotation is also moving parallel to itself, the body has both translatory as well as rotational motion. Sometimes, the the axis of rotation may be moving such that its one end moves on a cicle and the other is fixed like a spinning top. Some bodies have very general motion which can be described by more complex equations.
