Give the definition of coefficient of restitution .Prove that for perfect elastic collision of two bodies moving in the same line , the kinetic energy is conserved.

If the coefficient of restitution is zero for collision between two bodies then

If the coefficient of resittution is zero for collision between two bodies then

What are the characteristics of an elastic collision between two bodies ?

If there by perfectly elastic collision between two bodies of the same mass moving along a straight line, the two bodies will

Prove that the velocity get interchange in case of elastic collision of two objects of same mass.

Two bodies of different masses have the same momentum. Compare their kinetic energies.

A body of mass m moving with a velocity u strikes elastically a stationary body of mass 2m . After the elastic collision the bodies move with velocities v and V respectively . Show that the body of mass m loses 8/9 part of its initial kinetic energy.
