Energy

Energy is the ability to do workSound Energy: e.g. Instruments, radioElectrical Energy: e.g. LaptopKinetic Energy: e.g. Cycling, running, movingHeat Energye.g. Heater, animalLight Energy: e.g. Sun, light bulb

As energy is the ability to do work, it can be stored for late use - this is known as potential energy E.g. Any object that is raised into a position where it can fall, roll or slide downwards has gravitational potential energy. The higher something is the more GPE is stored in itE.g. Elastic potential energy is stored in things like compressed springs and stretched rubber bands.E.g Chemical energy is stored in the chemical substances found in batteries, wood, petrol, food and the cells of all living things.

Energy cannot be destroyed or created it can only be transferred or transformed.Energy transformation is when one form of energy changes into another form. E.g. electrical energy coming from a power plant transforming into light and heat energy in a light bulb.Energy transfer is when the form of energy stays the same, but it moves from one object to another. E.g. on a see-saw, the person at the high end has gravitational potential energy. As they go down this is transferred to the person on the other end
