Periodic: The motion of a body that repeats itself after a fixed time interval is called periodic motion. Rectilinear: The motion of a body along a straight line is called rectilinear motion. Rotational: The motion of a body which rotates on its own axis is called rotational motion. Circular: The motion of a body which follows a circular path is called circular motion. The distance between the centre of the circle and the object undergoing circular motion remains constant.

Match the events related to motion in Column I with the types of motions given in 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 moving wheel of the sewing machine rotates about its axis and hence has rotational motion. The motion of the earth around its axis is also rotatory motion. (b) Movement of tip of a minute hand of a clock in one hour - (i) Circular motion The tip of the minute hand of a clock is moving around the centre of the clock and is always equidistant from the centre of the clock. Hence, the motion is circular. (c) A moving swing - (iii) Periodic motion A moving swing moves to and fro with a certain time interval. Hence, its motion is periodic motion.

Four children measure the length of a table which was about $2 m$ . Each of them used different ways to measure it.

(i) Sam measured it with a half metre long thread.

(ii) Gurmeet measured it with a $15 cm$ scale from her geometry box.

(iii) Reena measured it using her hand span.

(Iv) Salim measured it using a $5 m$ long measuring tape.

Which one of them would get the most accurate length? Give reasons for your answer.
