Match the column I with column II . Column I Column II (a) A moving wheel of a sewing machine (i) Circular motion (b) Movement of the tip of the minute hand of a clock in one hour (ii) Rotational motion (c) A moving swing (iii) Periodic motion

(a) A moving wheel of a sewing machine - (ii) Rotational motion The wheel of a sewing machine rotates around itself and hence has rotational motion. The motion of the earth around its own axis is also rotatory. (b) Movement of the tip of the minute hand of a clock in one hour - (i) Circular motion A body is said to be possessed circular motion if it moves around a fixed point making equal distance from that point at any instance in its motion and the fixed point is called centre of circular motion. The movement of the tip of the minute hand of a clock in one hour follows a circular path and hence it is an example of circular motion. (c) A moving swing - (iii) Periodic motion The motion which repeats itself after a regular interval of time is known as periodic motion. The motion of a moving swing repeats itself after every oscillation and hence the motion is periodic.
