energy transformation
Changing energy forms
Energy transformation is the conversion of energy from one form to another.
A light bulb transforms electrical energy into light and heat.
Plants transform solar energy into chemical energy through photosynthesis.
The principle underlies all physical and biological processes—energy changes form but is neither created nor destroyed.
Also called energy conversion.
