Energy Types (Grade 8)

energy

Ability to do work

kinetic energy

Energy of motion

potential energy

Stored energy and object has which can change based on its position or shape

thermal energy

Thermal energy - fast the particles are moving the hotter the object is

electrical energy

Energy resulting in the movement of charged particles called electrons

chemical energy

The energy stored in the bonds between atoms, which can be found in food and fuel.

law of conservation of energy

Energy cannot be created or destroyed, only changed from one form to another

energy transformation

Takes place when energy changes from one form into another form.

sound energy

Energy that creates noise through vibrations, it can travel through a solid, liquid, and gas. It can not travel through a vacuum!

radiant energy (sun light)

Energy that has been released from the can be transformed into many other types of energy. It travels in waves and small packets of energy called photons.

mechanical energy

the sum of energy an object has because of the object's kinetic and potential energies.

elastic potential energy

potential energy stored in an object when an springy material deforms or changes shape.

force

A push or a pull

magnetic energy

energy from magnets and their surrounding magnetic fields. Magnets can move electrons in a wire

nuclear energy

Energy stored in the nucleus of an atom - the sun is an example

gravitational potential energy

Energy stored by objects due to their position above Earth's surface.

electromagnetic energy

A form of energy that travels through space as waves, x-rays, microwaves, and light are examples

work

W = fd Work equal force times distance
