An elastic collision is the one In which:
Correct answer: A. Kinetic energy and momentum is conserved
- A. Kinetic energy and momentum is conserved
- B. Kinetic energy is conserved but total energy is not conserved
- C. Momentum is conserved but kinetic energy is not conserved
- D. Both kinetic energy and momentum are not conserved
Explanation
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.

About Collisions
Collisions involve the conservation of linear momentum when bodies interact for a short time. The topic covers impulse, elastic and inelastic collisions, kinetic energy changes, and the coefficient of restitution, with calculations usually based on one dimensional motion. Momentum remains conserved in isolated collisions, but kinetic energy is conserved only in elastic collisions.
