Question

Is kinetic energy conserved in elastic collision?
explain it.
​

Answer 1

Answer:

An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions. This collision is perfectly elastic because no energy has been lost.

Please mark it as brainliest answer.

Answer 2

An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision .Both kinetic energy and momentum are conserved quantities in elastic collisions .Suppose two similar trolleys are travelling toward each other with equal speed.
