energy
energy In physics, capacity for doing
work. It is measured in
joules (J).
Power, the rate at which energy is produced or consumed, is measured in
watts (W).
Potential energy is an object's ability to do work because of a change in the object's position or shape.
Kinetic energy is the energy an object has because it is moving. Many forms of energy include electrical,
nuclear, thermal,
light and chemical. Energy can be transferred from one body to another through work processes, heating,
electromagnetic radiation and
electricity. The law of
conservation of energy states energy cannot be created or destroyed. Albert
Einstein established the idea that
mass is a form of energy, recognizing that energy (
E) and mass (
m) could be transformed into each other according to the relation E = mc
2, where c is the velocity of light.
