What is the process of saving up or storing energy?
Potential energy.
Energy that has the ability to fall; this type of energy increases the higher up you go.
Potential (gravitational) energy.
Energy is defined as _________.
The ability to do work!
Chemical to electrical to radiant to thermal

chemical to radiant to thermal to gravitational
What is energy in motion.
Kinetic energy.
"You can burn it or you can eat it."
Chemical energy.
the direct transfer of heat between objects that are in direct contact with each other. (heat transfer process)
conduction

Chemical to mechanical
Explain the energy transformation when a television is turned on. (3 steps)
electrical to radiant to sound
A heavy vase on a table has this type of energy.
(Gravitational) potential energy.
This type of energy is generated by a force - a push or a pull. Object is moving due to the force. (the body)
Mechanical energy.
Transfer of energy by currents through a liquid or a gas. (heat = rise, cold = sink)
Convection
Using a solar-powered calculator. (2 steps)
solar to electrical
As the mass of an object moving at a given speed decreases (50 mph to 25 mph) its kinetic energy will ______
Decrease
A person running down the sidewalk has this type of energy.
(Mechanical) kinetic energy.
The energy of vibrating air molecules
sound energy
Explain the law of conservation of energy!
Energy cannot be created or destroyed, it can only change forms!
