What is energy?

Look around you. Is anything moving?
Can you hear, see or feel anything? Sure... this is because something is making something happen, and most probably, there is some power at work. This power or ability to make things happen is what we can call energy. It makes things happen. It makes change possible.                        

Look at the sketch below to see an example of things working, moving, or happening... with energy.

Energy in action

Energy moves cars along the roads and makes aeroplanes fly. It plays our music on the radio, heats our rooms and lights our homes. Energy is needed for our bodies, together with plants to grow and move about.

Scientists define ENERGY as the ability to do work.
Energy can be neither created nor destroyed.

Let's start by looking at kinetic energy.
