In an elastic collision

A

the initial kinetic energy is equal to the final kinetic energy

B

the final kinetic energy is less than the initial kinetic energy

C

the kinetic energy remains constant

D

the kinetic energy first increases then decreases

Text Solution

Verified by Experts

The correct Answer is:
A
Due to deformation, kinetic energy decreases and during restoration, kinetic energy increases so that `K_(f) = K_(i)`.

Anwer carefully, with reasons: a) In an elastic collision of two billiard balls, is the total kinetic energy conserved during the short time of collision of the balls (i.e. when they are in contact)? Is the total linear momentum conserved during the short time of an elastic collision of two balls? c) What are the answers to a) and b) for an inelastic collision? d) If the potenital energy of two billiard balls depends only on the separation distance between their centers, is the collision elastic or inelastic? (note we are talking here of potential energy corresponding to the force during collision, not gravitational potential energy).

STATEMENT-1 : In an elastic collision between two balls, the total kinetic energy of the two bodies does not remain conserved during the collision. and STATEMENT-2 : As the balls collide, they compress each other.

STATEMENT - 1 : Two identical balls B and C lie on a horizontal smooth straight groove so that they are touching. A third identical ball A moves at a speed v along the groove. And collides with B as shown in figure. If the collisions are perfectly elastic, then after the collision, balls A and B will come to rest and ball C moves with velocity v to the right. because STATEMENT - 2 : In an elastic collision, linear momentum and kinetic energy are both conserved.
