During collision kinetic energy is conserved at each instant

The kinetic energy is conserved in

The kinetic energy is not conserved in

Assertion : In elastic collision, kinetic energy is conserved. Reason : Energy is always conserved.

Assertion : In elastic collision, kinetic energy is conserved. Reason : Energy is always conserved.

In the following question, a statement of Assertion is followed by a statement of Reason. Mark the correct choice. Assertion: In an elastic collision of two billiard balls are in contact with each other. During the short time of collision, kinetic energy is conserved. Reason: Energy, spent against friction does not follow the law of conservation of energy

Assertion: The conservation of kinetic energy in elastic collision applies after the collision is over and does not hold at every instant of the collision. Reason: During a collision the total linear momentum is conserved at each instant of the collision.

Assertion: The conservation of kinetic energy in elastic collision applies after the collision is over and does not hold at very instant of the collision. Reason: During a collision the total linear momentum is conserved at each instant of the collision.

Assertion:The principal of conservation of energy is valid for inelastic collision. Reason: The principal of conservation of energy holds good in both elastic and inelastic collision. In case of inelastic collision kinetic energy before and after collision is not same.
