What is oil used for?
Oil is used for fuel for cars trains ships and planes. It is also used as a heating oil and is used to make plastics cosmetics and medicines.
What is natural gas used for?
Natural gas is used for fuel for buses and trucks and to heat homes.
What is potential energy?
Potential energy is stored energy or about to be used energy.
What is kinetic energy?
Kinetic energy is energy in motion.
What is solar energy used for?
Solar plants generate electricity. Solar cells are used to power calculators lights telephones and other small devices.
What does wind do?
Wind turbines produce electricity
What does flowing water do?
Flowing water turns turbines to produce electricity.
What is coal used for?
Coal is burned to provide electricity
What is biomass used for?
Biomass is used as fuel for cars and trucks. Methane gas is used to heat buildings.
What is geothermal energy used for?
Used to heat homes and produce electricity
What is nuclear energy used for?
Nuclear energy is used to produce electricity.
What is a fossil fuel?
And energy rich substance formed from the remains of prehistoric organisms.
Why are some things nonrenewable?
because it takes too long for it to make.
What is electricity?
The results of moving electrons.
What is mechanical energy? What are some examples?
Energy associated with the motion or position of an object.
Examples:
- ball moving through the air
- waterfall
- car moving down the street
What is a thermal energy? What are some examples?
The measure of the energy of the particles in an object.
Examples:
- melting ice cubes
- melting ice cream

What is radiant energy? What are some examples?
Light energy that travels up and down in waves.
Examples:
- rainbows
- photosynthesis
What is nuclear energy? What are some examples?
The type of energy stored in the Nucleus of an atom that releases during a nuclear reaction
Examples:
- nuclear bomb
- nuclear power plant
- nuclear rods
What does burning fuel do in a simple generator?
The fire produces heat which produces steam.
What does the steam do?
It’s forces the fan turbine to spin
What does the fan do?
It makes the magnet spin inside the coil producing electricity.
What is voltage?
Voltage is the way we measure the amount of electricity in an object.
