What is meant by an energy store?

Energy cannot be created or destroyed. It can be stored, or it can be transferred i.e. from a hot object to a cool object by conduction, convection or radiation.

What is the difference between a fuel and an energy store?

You can describe the ability of a fuel, such as petrol, to get a job done by saying that it has an energy store associated with it. As the fuel does its job (maybe propelling a car along the road), energy is shifted from the store. Given the source of the energy (the petrol), we say that this is a chemical store.

What is the difference between energy stores and transfers?

Where there are energy transfers in a system , the total energy associated with the system stays the same. Energy is measured in joules (J)….Energy stores.

Energy store Description Examples
Chemical The energy store associated with chemical bonds, such as those between molecules. Food, muscles, electrical cells.
