Key Stage 3
Meaning
An energy store is a way in which energy can be kept in a system.
About Energy Stores
- Energy Stores are associated with the movement or objects and position of objects in a field.
- There are some energy stores you should know at this stage:
Thermal Energy Store
The energy store associated with the temperature of an object. The higher the temperature the more the particles vibrate and faster they move in the material storing energy. |
Elastic Potential Energy Store
The energy store in stretched, squashed and twisted elastic objects. |
Chemical Potential Energy Store
The 'energy in chemicals that can be released in a chemical reaction. |
Kinetic Energy Store
The energy store of a moving object. |
Magnetic Potential Energy Store
The energy store of a magnetic object in a magnetic field. |
Electrostatic Potential Energy Store
The energy store of a charged object in an electric field. |
Nuclear Potential Energy Store
The energy store associated with Nuclear Fuel. |
Gravitational Potential Energy Store
The energy store of an object in a gravitational field. |
Key Stage 4
Meaning
Energy stores are the different ways in which energy can reside in a system.
About Energy Stores
- Energy Stores are associated with the movement of objects and position of objects in a field.
- There are a number of energy stores that can be used to describe a system:
- Thermal Energy Store - Particles vibrating or moving around randomly in the material store energy.
- Elastic Potential Energy Store - A stretched, squashed or twisted object stores energy.
- Chemical Potential Energy Store - Chemicals store energy that can be released in chemical reactions.
- Kinetic Energy Store - An moving objects stores energy.
- Magnetic Potential Energy Store - A magnetic object in a magnetic field stores energy.
- Electrostatic Potential Energy Store - A charged object in an electrostatic field stores energy.
- Nuclear Potential Energy Store - The nucleus of an atom stores energy that can be released in Nuclear Reactions.
- Gravitational Potential Energy Store - An object in a gravitational field stores energy.
- Internal Energy Store - A combination of the thermal energy store and all potential energy stores of the particles in an object.
- Vibrational Energy Store - A combination of energy stores that can be used to describe a vibrating object. For example a spring going up and down transfers energy between the kinetic energy store, elastic potential energy store and the gravitational potential energy store but this can be described more simply as the spring having a Vibrational Energy Store.
