Energy

Energy is the ability to do work

Potential Energy

• stored energy due to a body's position or condition.

Chemical potential energy

• the energy stored in fuels such as petrol and food
• can be released through chemical reactions

Gravitational potential energy

• the energy an object has because of its position or location

Elastic potential energy

• the energy an object has when it is stretched or compressed

Kinetic energy

• the energy that a body has due to its motion

Heat energy

• the energy that flows from a region of higher temperature to one at lower temperature

Light energy

• the energy that enables us to see

Sound energy

• the energy produced when objects vibrate
• allows us to communicate

Electrical energy

• the energy that results from the flow of charged particles
• can be transformed into many other forms of energy
