Energy

Look at the following pictures - what can we say about the energy in each example: - – Where do you think the energy comes from?– What type of energy is being used?

Vibrating drum & plucked guitar string: -

Energy is transferred from you, as you hit the drum or pluck the string

The energy is transferred to the surroundings as sound energy

Energy

Rock on a mountain: -

The rock has stored energy because of its position above the ground and the pull of gravity (gravitational potential energy). If the rock fell, this gravitational potential energy would be transferred as kinetic energy

A battery & light bulb: -

Energy is stored chemically, and is transferred as electrical energy. Electrical energy is transferred to the surroundings as light and thermal (heat) energy via the bulb

Energy

Explosives: -

Energy is stored chemically, and when detonated this is transferred to the surroundings as thermal energy, sound energy and kinetic energy

Hot tea: -

Hot tea has heat energy in the form of kinetic energy (moving particles). Some energy is transferred to cold milk when it is poured in, lowering the tea’s temperature

Energy

Energy is the ability to ‘do some work’ - everything that happens needs energy (e.g. heating; cooking; lighting; movement of vehicles; and keeping us alive)!

Energy cannot be created or destroyed, only transferred from place to place in a variety of ways

Types Of Energy

1. Electrical energy - a current in a circuit etc…2. Light energy - from the sun; a light bulb etc…3. Sound energy - from a loudspeaker; a drum etc…4. Kinetic (movement) energy - anything which moves!5. Nuclear energy - transferred during a nuclear reaction6. Thermal (heat) energy - transferred from hot objects to colder

ones7. Radiant heat (infra red) energy - transferred as

electromagnetic radiation by hot objects8. Gravitational potential energy - possessed by anything with

the ability to fall9. Elastic potential energy - stretched springs; elastic and rubber

bands etc…10. Chemical energy - possessed by food; fuels; batteries etc…

Energy Superhero

Your task is to create a super-hero which displays all the types of energy there are…

E.g. Mr. Energy has elastic potential energy in his spring legs; chemical energy in his battery pack; and nuclear energy via his nuclear booster pack etc…

When you create your superhero you must explain where each of the energy types are found on them…
