What is gravitational potential energy?
Heat moves from a ______ object to a ______ object.
What is warmer to cooler?

What is chemical potential energy?
Heat transfer due to touch.
What is conduction?
Energy that is formed by the joining of atoms with a force.
What is fusion?
An object at the top of a hill has mechanical energy because it has ______ energy.
