What is the relationship between the speed of an object and the energy it can transfer?

Back

As an object moves faster, it has more energy to transfer.

How does energy conservation apply to collisions?

Back

In a closed system, the total energy before and after a collision remains constant.

Front

What is an elastic collision?

Back

An elastic collision is one in which both momentum and kinetic energy are conserved.
