Answer:

In an elastic collision:

There is no external net force acting. Thus, Momentum before and after collision is equal. Momentum remains conserved.

Total energy always remains conserved as energy cannot be created nor destroyed. It can change from one form to another.

There is no lost due to friction in elastic collision. So the kinetic energy is also conserved.

Velocities may change after collision. If the masses are equal, the velocities interchange.

When one object is stationary:

Final velocity of object 1:

v₁ = (m₁ - m₂)u₁/(m₁ +m₂)

Final velocity of object 2:

v₂ = (2 m₁ u₁)/(m₁+m₂) =

Objects do not stick together in elastic collision. They stick together in inelastic collision.

Thus, conditions for an elastic collision:
