Question

(A) The correct answer is $A$.In an elastic collision,kinetic energy $(KE)$ is conserved throughout the entire process,including during the collision

Vedclass · Accepted Answer

In elastic collision,$KE$ is not conserved during the collision.

Vedclass · Answer

(A) The correct answer is $A$.In an elastic collision,kinetic energy $(KE)$ is conserved throughout the entire process,including during the collision phase. Therefore,the statement that $KE$ is not conserved during the collision is false.Regarding option $D$,the momentum of the ball is $NOT$ conserved because an external impulsive force (the normal force from the floor) acts on the ball during the collision. However,in the context of multiple-choice questions where one must identify the most fundamentally incorrect statement regarding definitions,option $A$ is explicitly false by the definition of an elastic collision.
