Energy Flashcards
Magnetic energy
The energy stored when repelling poles have been pushed closer together or when attracting poles have been pulled further apart.
Examples of magnetic energy stores
Fridge magnets, compasses, maglev trains which use magnetic levitation.
Thermal energy
The total kinetic and potential energy of the particles in an object, in most cases this is the vibrations - also known as the kinetic energy - of particles. In hotter objects, the particles have more internal energy and vibrate faster.
Examples of thermal energy stores
Human bodies, hot coffees, stoves or hobs. Ice particles vibrate slower, but still have energy.
Chemical energy
The energy stored in chemical bonds, such as those between molecules.
Examples of chemical energy stores
Foods, muscles, electrical cells.
Kinetic energy
The energy of a moving object
Examples of kinetic energy
Runners, buses, comets.
Electrostatic energy
The energy stored when repelling charges have been moved closer together or when attracting charges have been pulled further apart.
Examples of electrostatic energy
Thunderclouds, Van De Graaff generators.
Elastic potential energy
The energy stored when an object is stretched or squashed.
Examples of electrostatic energy
Drawn catapults, compressed springs, inflated balloons.
Gravitational potential
The energy of an object at height.
Examples of gravitational potential energy
Aeroplanes, kites, mugs on a table.
Nuclear energy
The energy stored in the nucleus of an atom.
