Question

In case of elastic collision, at the time of impact, total k.e of colliding bodies
a) is conserved
b)increases
c)decreases
d)none of the above

Answer 1

In case of elastic Collision, at the time of impact, the total Kinetic energy of colliding bodies

(a) is conserved

Even the momentum remains conserved.

While in inelastic collision only momentum remains conserved not the kinetic energy.
