(b) Moving ball hitting ruler placed in its path	(ii) Change in Shape
(c) Stretching and releasing a string	(iii) Change in Direction

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

Answer 1

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

i. A fielder catching a moving ball, demonstrates that a force can stop a moving object as the object comes to rest here. Therefore there is a change in state of motion.
ii. The moving ball changes its direction when it strikes the ruler placed in its path.
iii. There is a temporary change in the shape of the spring by stretching it in the opposite directions.
