4.2 Describe energy transfers involving the following forms of energy: thermal (heat), light, electrical, sound, kinetic, chemical, nuclear and potential (elastic and gravitational)

There are 9 types of energy (stated in the specification point). Energy is transferred all the time, all around us. Some examples of energy transfers include:

• Chemical to thermal energy (fireplace kind of fire - the wood provides chemical E.)
• Gravitational potential to kinetic energy (pendulum)
• Electrical to light and sound energy (TV)
• Nuclear to electrical energy (power station)
• Elastic to kinetic energy (bow and arrow)

An example of how energy can be transferred
