Physics
Give two examples to illustrate that a body can have two or more types of motion simultaneously.
Answer
The two examples that show a body can have two or more types of motion (mixed motion) simultaneously are:
The Earth rotates about its axis (rotatory motion) and at the same time, it revolves around the sun in a curved path (curvilinear or circular motion) in a fixed time interval (periodic motion).
A ball rolling on the ground has rotatory and translatory motion as it moves on the ground.
