Question 16
Match the events related to motion in Column I with the types of motions given in Column II.
COLUMN II COLUMN II(a) A moving wheel of a(i) Circular motion sewing machine(b) Movement of tip of the minute(ii) Rotational motion hand of a clock in one hour(c) A moving swing(iii) Periodic motion
a) Rotational motion is the motion of an object in a circular path about a fixed axis. So, (a) corresponds to option (ii).
(b) Circular motion is the motion of an object along a circular path. So, (b) corresponds to option (i).
(c) Periodic motion is the motion that repeats itself after some period of time. So, (c) corresponds to option (iii).
