Explain what part of the scenario is considered potential energy: Suzy stands in line while she waits to enter into the roller rink. She takes a step into the rink and pushes off while she skates with her friends.
While waiting in line, Suzy's body is storing the potential energy. The potential energy will transfer into kinetic energy once she pushes her feet and the wheels roll.

What form of energy do solar panels use to generate electricty?
Light (in the form of solar radiation)
300
What am I? Combustible black or brownish-black sedimentary rock composed mostly of carbon and hydrocarbons.
coal

Biomass is a potential energy that turns into what form of energy when burned?
Heat
400
Airflows can be used to run w_____ t_______ and this produces e______ in buildings and homes.
wind turbines, energy
400
Are all fossil fuels nonrenewable? why?
No,they were formed from the buried remains of plants and animals that lived millions of years ago.

Explain the energy transfer when turing on a light switch.
When a light switch is turned on, electrical energy runs through the wires and is transferred to the bulb where electrical energy is converted to light and heat energy.
400
Can you create or destroy energy? Explain. A.Yes B.No C.Only if you are really strong
B. No Energy can't be created or destroyed, but it transforms from one form to another
