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..
netwons
People who dig holes in the road need a lotof 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 theywork.
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.
How do we describe the way that energy is stored in batteries and food?
kinetic energy
chemical energy
thermal energy
potential energy
Which of these is NOT a way of transferring energy?
light
forces
heating
strain
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.
Fossil fuels are formed from:
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 run out one day.
Renewable energy resources will not run out.
Non-renewable energy resources will not run out.
None of our energy resources will run out.
Coal has energy stored in it because it is black.
Fossil fuels have energy stored in them because the animals that became fossils ran around a lot.
Coal has energy stored in it because it is warm inside the Earth.
The plants that formed coal got their energy from the Sun.
Which of these energy resources does not originally come from the Sun?
wind energy
solar power
fossil fuels
geothermal energy
Which of the following is not true?
Energy can be transferred to heat things.
Energy can be destroyed.
Energy is stored in fossil fuels.
Energy can be stored.
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 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.
