Question

Match the entries of column I with column II.

Activity	Type of Motion
(a) Elevator motion	(i) Oscillatory motion
(b) Pendulum of a clock	(ii) Rotational motion
(c) Movement of the merry-go-round	(iii) Linear motion

• A. (a) - (iii), (b) - (i), (c) - (ii)
• B. (a) - (ii), (b) - (i), (c) - (iii)
• C. (a) - (ii), (b) - (iii), (c) - (i)
• D. (a) - (i), (b) - (iii), (c) - (ii)

Answer 1

The correct option is A (a) - (iii), (b) - (i), (c) - (ii)

Motion of an elevator is a linear motion as it travels in a straight line.
The motion of the pendulum of a clock represents oscillatory motion as the pendulum swings to and fro continuosly.
You might have seen a merry-go-round in amusement parks. When they are in motion, each part of it moves in a circular path with a fixed radius. Hence, the motion of a merry-go-round is an example of rotational motion.
