Energy
I can identify different energy stores that objects have and explain why they have each energy store.
Lesson details
Key learning points
- Objects can have energy because they are: moving, raised, hot, stretched/squashed, or contain chemicals that can react.
- When an object is said to have energy, this is really just saying the object has certain properties.
- Objects can have gravitational, thermal, elastic, chemical and kinetic stores of energy.
- Having energy means having properties that allow objects to interact, cause changes and make things happen.
Keywords
Chemical store - Objects that contain chemicals that can react, have a chemical store of energy.
Thermal store - Objects have a thermal store of energy because of their temperature.
Kinetic store - Objects that are moving have a kinetic store of energy.
Gravitational store - Objects that are raised up have a gravitational store of energy.
Elastic store - Objects that are stretched or squashed have an elastic store of energy.
Common misconception
Energy is some sort of physical substance that objects have.
Energy is just a label for having certain properties. The properties are what allow objects to interact / cause change / make things happen.
