The Seven Different Types of Energy Stores - Physics Revision (Years 7, 8 & 9)

Gravitational Potential Energy Stores00:00:16

Gravitational potential energy is stored in any object that can fall within a gravitational field. The higher the object, the more gravitational potential energy it possesses. Examples include a ball at the top of a ramp, a skier on a mountain, and an apple falling from a tree.

Chemical Energy Stores00:01:15

Chemical energy is released through chemical reactions. Common examples of items with chemical energy stores include batteries, food (like pizza), and fuels (such as gas in a canister).

Kinetic Energy Stores00:01:53

Kinetic energy, also known as movement energy, is present in any object that is moving. This includes people, animals, and vehicles. Examples shown are runners, a rocket, a footballer, and a car.

Elastic Potential Energy Stores00:02:47

Elastic potential energy is stored in objects that can be stretched or compressed. Examples include slinky springs, elastic bands, hair scrunchies, and elastic in clothing like underwear.

Electrostatic Energy Stores00:03:33

Electrostatic energy exists between objects with electric charges that attract or repel each other. This is seen in electrical currents where charged particles move through a wire. Examples include wires from plugs, static electricity generated by a comb, and the national grid pylons.

Magnetic Energy Stores00:04:21

Magnetic energy is found between two magnets that can attract or repel each other due to a magnetic field. Images of various magnets and iron filings demonstrating a magnetic field are used as examples.

Thermal Energy Stores00:05:03

Thermal energy is present in anything that heats up. The hotter an object, the more thermal energy it stores. Examples include a fire, a Bunsen burner, a campfire, and a lamp bulb that warms up when lit.
