When do we say that rigid bodies exhibits both translational and rotational motion?
A translational motion is one when the motion of a body can be described with the help of only one co-ordinate(either X or Y or Z).In simple words,translational motion is actually the linear motion of the body. Ex. motion of a vehicle in a straight direction, Rotational motion is one in which each particle of a body always maintains same distance with the reference axis within that body called as “Axis of rotation”. Ex.Rotation of earth over its own axis,rotation of a top,etc. Now,examples of a body performing rotational and translational motions simultaneously are moving of a cricket ball on the field,moving of any round object over the horizontal surface.
