In an elastic collision, what happens to the total kinetic energy of the system?

• It increases.

• It decreases.

• It remains the same.

• It becomes zero.

What is the main difference between elastic and inelastic collisions?

• In elastic collisions, objects stick together after collision, while in inelastic collisions, they do not.

• In elastic collisions, total kinetic energy is conserved, while in inelastic collisions, it is not.

• In elastic collisions, momentum is not conserved, while in inelastic collisions, it is.

• In elastic collisions, objects change their shape, while in inelastic collisions, they do not.
