Forms of energy

There are 9 forms of energy

Kinetic and gravitational energy

Kinetic energy is energy that is moving and is in motion. Gravitational potential energy is the force that attracts an object towards the centre of the earth. Two examples of kinetic energy is a person moving. A ball falling shows both kinetic and gravitational potential energy. One more of gravitational potential energy is someone jumping and coming back down.

Chemical energy

Chemical energy is energy stored in the bonds of chemical compounds (atoms and molecules). It is released in a chemical reaction. Two examples are mixing two different coloured liquids together and burning something.

Heat and light energy

  1. Heat energy is the result of the movement of tiny particles called atoms. Heat energy can be transferred from one object to another, and the transfer is due to the difference in temperature. Light is a form of energy which our sense of sight can detect. It is made of electro-magnetic radiation and travels in a straight path. Two examples of light energy can be the sun. A light bulb that is on is both light and heat energy. An other example of heat energy is a heater that is turned on.

Nuclear energy

  1. Nuclear energy is the energy released during nuclear fission or fusion and especially when used to generate electricity. Two examples can be a nuclear bomb going off and nuclear weapons getting built.
