What is radiation?
State the Type of Energy:
A roller coaster at the top of a large hill has more gravitational potential energy than it does at the bottom. This change results in a hair-raising ride.
What is Gravitational Potential Energy?
A _______ system can exchange energy, but not matter, with its surroundings.

A 45 kg boulder is sitting on a cliff that is 125 m high.
What is 5.5 × 10 ^4 J or 55,000 J
State the Type of Energy:
The energy of random motion of particles in a substance
What is Thermal Energy?
Describe this Energy System:
An uncovered pot of potatoes boiling on the stove. system. Thermal energy is transferred from the stove burner to the pot and its contents, as well as to the surrounding cooler air.
As the water boils, thermal energy is also transformed into the mechanical kinetic energy of rising steam. As the steam leaves the pot, the system loses both matter and energy to the surroundings.
What is an Open System?
