Potential
What type of energy is this an example of:
A person eating food
Chemical energy, kinetic energy, sound energy
Name the 3 NONRENEWABLE resources:
Hint-CON
Coal, Oil, Natural Gas
What two energies does this example transfer to and from:
A light is turned on and off
Electrical to light and thermal
True or false: solar energy is renewable energy
TRUE
P or K? A person is talking.
Kinetic
What is another word for THERMAL energy?
Heat energy
What is the difference between a renewable resource and a nonrenewable resource?
Nonrenewable resources run out because they are fossil fuels.
Renewable resources will never run out, because they can be used again and again.
