In this question, we are given with some statements regarding the elastic collision between two perfectly rigid objects.
00:12
Statement a is given as the momentum of each object is conserved in the collision.
00:23
The momentum of object before and after the collision in elastic collision is conserved.
00:35
The statement is true.
00:41
Statement b, the kinetic energy of each object is conserved.
00:51
For an elastic collision, the kinetic energy before the collision and after the collision is conserved.
01:02
So the statement b is also true.
01:08
Statement c, the momentum of the system is conserved but the kinetic energy of the system is not conserved this statement is false because both kinetic energy and momentum is concerned in an elastic collision so statement c is false statement d is given us both the momentum and kinetic energy of the system both momentum and and kinetic energy are conserved.
02:00
So the statement d is true.
02:04
Statement e is given.
02:08
The kinetic energy of the system is concerned, but the momentum of the system is not concerned.
02:19
Momentum not conserved.
02:23
In elastic collision, both the momentum and kinetic energy is conserved.
02:28
So the statement e is false...
