Question

Match column I with column II and select the correct option from the given codes.

Column I	Column II
(a)	(i) Rectilinear motion
(b)	(ii) Periodic motion
(c)	(iii) Oscillatory motion

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

Answer 1

The correct option is C (a)-(ii); (b)-(ii); (c)-(ii), (iii)

Rectilinear motion: Motion in a straight line
Periodic motion: Motion that repeats itself after a fixed interval of time
Oscillatory Motion: To and fro motion

Earth rotating around the sun exhibits periodic motion since it takes exactly 1 year every time for it to complete one revolution around the sun.
The hands of a clock also exhibit periodic motion since they repeat their motion after a fixed interval of time.
A pendulum exhibits oscillatory motion. It also exhibits periodic motion since it repeats its motion after a fixed time period.
