Vedclass · Answer

(A) During the collision of two elastic bodies,the bodies undergo deformation. At the point of maximum deformation,the relative velocity of the bodies becomes zero. At this instant,a part of the kinetic energy of the system is converted into elastic potential energy due to the deformation of the bodies. Therefore,the kinetic energy of the system decreases during the time of collision. This decrease in kinetic energy is stored as elastic potential energy because the intermolecular distances change (decrease) during deformation. Thus,both the $Assertion$ and $Reason$ are correct,and the $Reason$ is the correct explanation for the $Assertion$.

$Assertion$ : If collision occurs between two elastic bodies their kinetic energy decreases during the time of collision.
$Reason$ : During collision intermolecular space decreases and hence elastic potential energy increases.
