When two bodies collide elastically, then

Question -

When two bodies collide elastically, then

Options:

A . Kinetic energy of the system alone is conserved

B . Only momentum is conserved

C . Both energy and momentum are conserved

D . Neither energy nor momentum is conserved

Answer: Option C
:
C

By definition of perfectly elastic collision, both Momentum and Kinetic energy of the system are conserved.
