We get the energy that our bodies need from energy stored in:
food
water
warm clothes
hot baths
The units for measuring energy are:
Horsepower
degrees
Joules
Newtons
People who dig holes in the road need a lot of energy stored in their food because:
they have long tea breaks.
they always forget their sandwiches.
they sometimes have to work in the rain.
they transfer a lot of energy while they work.
You can find out how much energy is in a peanut by:
burning it, and seeing how hot it makes a test tube of water.
eating it, and seeing how full you feel.
weighing it.
seeing what colour it is.
Fossil fuels are formed from:
water
electricity
dead plants and animals
rocks
Fossil fuels are non-renewable fuels because:
they give out heat when they burn.
they were formed from fossils.
they are expensive.
they cannot be replaced once they are burnt.
Electricity is not a fuel because:
it has to be generated using other energy resources.
it is easy to switch on and off.
it cannot be used to make cars run.
it can burn you.
Which statement is true?

Renewable energy resources will not run out.
Non-renewable energy resources will not run out.
None
Which renewable resources are available at any time?
hydroelectricity and geothermal
solar and wind
tidal and wave
biofuels and solar energy
Which of these energy resources does not originally come from the Sun?
wind energy
solar power

geothermal energy
How could we use less fuel for heating our homes?
Keep the house warmer and open the windows.
Keep the house cooler and wear a jumper.
Make sure we leave the heating on when we are out.
Turn the heat up at night, so we don’t need blankets on the bed.
Which of these is not a problem with using energy resources?
Burning fossil fuels releases carbon dioxide into the atmosphere.
Wind turbines do not produce carbon dioxide.
Solar energy is not available during the night.
Nuclear fuel gives off dangerous radiation.
Why do we need to burn fewer fossil fuels?
Burning fossil fuels is contributing to climate change.
Electricity is running out.
To pay for new cars.
Energy is cheap.
How do we describe the way that energy is stored in batteries and food?
kinetic energy
chemical energy
thermal energy
potential energy
Which two stores is energy transferred between when you heat a pan of water on a gas cooker?
thermal to chemical
electrical to thermal
chemical to thermal
kinetic to strain
A stretched bow is a store of energy (strain energy). What happens to the energy when the arrow is fired?
Forces transfer the energy to kinetic energy in the arrow.
Energy is stored as chemical energy.
Movement energy is transferred to sound energy.
Force energy is transferred by movement.
