|Statement-1: If collision occurs between two elastic bodies their kinetic energy decreases during the time of collision.|
|Statement-2: During collision intermolecular space decreases and hence elastic potential energy increases.|
A) Statement-1 is true, Statement-2 is true; Statement-2 is a correct explanation for Statement-1.
B) Statement-1 is true, Statement-2 is true; Statement-2 is not a correct explanation for Statement-1.
C) Statement-1 is true, Statement-2 is false.
D) Statement-1 is false, Statement-2 is true.
Correct Answer: A
Solution :During the time of collision between two elastic bodies, elastic potential energy increases as a result of decrease in intermolecular space. Hence, kinetic energy decreases during that time. Note that kinetic energy doesn't change after collision.
