Types Of Energy
To know all types of energy
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
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
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
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
Explosives: Energy is stored chemically, and when
detonated this is transferred to the
surroundings as thermal energy, sound
energy and kinetic energy
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

Electrical energy - a current in a circuit etc…
Light energy - from the sun; a light bulb etc…
Sound energy - from a loudspeaker; a drum etc…
Kinetic (movement) energy - anything which moves!
Nuclear energy - transferred during a nuclear reaction
Thermal (heat) energy - transferred from hot objects to colder
ones
Radiant heat (infra red) energy - transferred as
electromagnetic radiation by hot objects
Gravitational potential energy - possessed by anything with
the ability to fall
Elastic potential energy - stretched springs; elastic and rubber
bands etc…
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…
