What is an energy store?

Something such as food or hot objects that enables you to account for the energy at the start and end of a transfer

Kinetic energy

What type of energy store is in a battery

Chemical energy store

What does the law of conservation of energy say?

Energy cannot be created or destroyed, only transferred

What unit is work measured in

What are all the different ways to store energy?

Most kids hate learning GCSE energy names: magnetic, kinetic, heat, light, gravitational, chemical, sound, electrical, elastic, nuclear.

The amount of radiation depend on what 2 factors?

The surface (colour and texture) AND the temperature

If an object is hotter, will it emit more or less radiation?

More

If an object is black, it will both emit AND absorbs more thermal radiation? True or false?

True

If an object is shiny, will it absorb more or less thermal radiation?

Less because it reflects it.

What are the ways of transferring energy between different stores?

Light, sound, electricity

A coal fire is burning in the fireplace. Describe the energy before and after

Before the energy is stored in the coal as a chemical store after the energy is transformed into thermal energy light energy sound energy and kinetic energy of hot gasses
