14. Forms of Energy CHEMICAL ENERGY
This is energy that is released when chemical reactions take place.
Sources of chemical energy include:
fuel, food and batteries

15. Forms of Energy KINETIC ENERGY
Gravitational potential energy being converted into kinetic energy.
KINETIC ENERGY
This is the energy possessed by a moving object.
Kinetic energy increases is the object’s speed is increased.
GRAVITATIONAL POTENTIAL ENERGY
This is the energy possessed an object due to its position.
The gravitational potential energy of an object increases if it is raised upwards.

16. Forms of Energy ELASTIC ENERGY
This is the energy stored in a stretched or squashed object
- also known as strain energy
ELECTRICAL ENERGY
This is the energy transferred by an electric current.
SOUND ENERGY
This is energy in the form of a sound wave.

17. Forms of Energy THERMAL ENERGY
This is the energy of an object due to its temperature.
- also known as heat energy
LIGHT ENERGY
This is energy in the form of visible electromagnetic radiation.
NUCLEAR ENERGY
This is energy that is released when nuclear reactions take place.
This is the source of the Sun’s energy.

18. Useful and Wasted Energy
Useful energy
This is energy transferred to where it is wanted in the form it is wanted.
Wasted energy
This is energy transferred to where it is not wanted in the form it is not wanted.

19. Energy Flow Diagrams

20. An electric light bulb
