Forms of energy
Sound energy
Sound energy
Sound energy is a form of energy that is associated with vibrations of matter. It is a type of mechanical wave which means it requires an object to travel through. This object includes air and water.

Heat energy
Heat energy
Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another, and the transfer or flow due to the difference in temperature between the two objects is called heat.

Light energy
Light energy
Light energy is defined as how nature moves energy at an extremely rapid rate, and it makes up about 99% of the body's atoms and cells, and signal all body parts to carry out their respective tasks. An example of light energy is the movement of a radio signal.

Kinetic energy
Kinetic energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Chemical energy
Chemical energy
The energy that results during a chemical reaction is called chemical energy. It is a type of potential energy. Chemical energy is stored within the bonds of the atoms and molecules that make up a substance. Once chemical energy is released from a substance, the substance is transformed into a new substance.

Nuclear energy
nuclear energy
Nuclear power is the use of nuclear reactions that release nuclear energy, to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear powerstation. The term includes nuclear fission, nuclear decay and nuclear fusion.

Gravitational potential energy
Gravitational energy
Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitationalacceleration can be assumed to be constant at about 9.8 m/s2.

Elastic potential energy
Elastic potential energy
Elastic potential energy is Potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring. It is equal to the work done to stretch the spring, which depends upon the spring constant k as well as the distance stretched.
