Give two examples to illustrate that a body can have two or more types of motion simultaneously.
Sometime a body can have more than one type of motion. Such a motion is called the mixed motion.
(i) The wheels of a moving train have both the translatory as well as the rotatory motions as it moves from position A to position B while rotating.
(ii) 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).
