In an elastic collision
A. the kinetic energy remains constant

B. the linear momentum remains constant

C. the final kinetic energy is equal to the initial kinetic energy

D. the final linear momentum is equal to the initial linear momentum.

Answer :

We know that, in all collisions, momentum is conserved as no external forces are present. SO B and D are correct. Now, coming to energy, in elastic collision, final and initial kinetic energies are same but it is not conserved throughout the collision. So, C is correct but not A.
