Eight Forms of Energy
1. Electrical Energy
This is a very useful form of energy, because it's easily converted into other forms
wherever there's a current flowing, there's electrical energy.
2. Light Energy
Anything luminous gives off light energy, - things like the Sun, light bulbs and
candles... and glow worms.
3. Sound Energy
Anything noisy gives off sound energy, - thins like vocal chords, speakers and
4. Kinetic (Movement) Energy
Anything that moves has kinetic energy.
5. Thermal (Heat) Energy
Anything with a temperature above absolute zero (-273 degrees C) has heat energy
obviously, that means everything has some heat energy. The hotter something - is
the more heat energy it has.
6. Gravitational Positional Energy
Anything that is above the ground has potential energy, - i.e. anything that can fall,
like ski jumpers, aeroplanes and climbers.
7. Elastic Energy
Anything stretchy has elastic energy, - things like rubber bands, springs, knicker
8. Chemical Energy
Anything with stored energy which can be released by chemical reaction things like
food, fuels and batteries.
Heat and Temperature and Different
Temperature is a measure of how hot something is it's measured in degrees Celsius. Heat
is not the same thing. Heat is a form of energy and it's measured in joules, (J). Heat (energy)
flows between things that have different temperatures. Temperature isn't a form of energy
and temperature doesn't flow. When heat energy flows, then the temperature increases
