Back

kinetic energy is the energy of motion, which is what happens as water falls.

Front

Energy stored in the nucleus of an atom is called _____________.

Back

nuclear energy is the energy released during nuclear reactions, such as fission or fusion.

Front

A change in an object's speed has a(n) ______________________ effect on its kinetic energy than a change in its mass.

Back

greater effect; kinetic energy increases with the square of the speed.

Front

The gravitational potential energy of an object is equal to its weight multiplied by its _____________.

Back
