Forms of energy
- Mechanical (potential & kinetic)
- Sound
- Heat
- Light
- Chemical
- Electrical
- Deformation (elastic)
- Nuclear
Mechanical
Everyday thing
Potential = the possibility of gravity pulling something down
Kinetic = motion, something moving
Sound
An object vibrating
Heat
Molecules & atoms moving
Light
Electromagnetism radiation, sometimes visible to the human eye
Chemical
Uses fuel or food, bonds are broken and formed between molecules and atoms
Electrical
Electrons are moving in a current
Deformation
Elastic, object is bouncy or stretchy
Nuclear
An objects nucleus splits apart or is fused together
Something that is at its highest point…
Has no kinetic energy
The main function of a solar panel is to convert …
Light energy —> electrical energy
