10 Difference Between Energy And Power

1. SI unit: Energy: Joules Power: Watt 2. Energy is the capacity to do work. Power is the rate at which work is done. 3. ‘W’ is the symbol which denotes energy. The symbol used to denote power is P. 4. Energy is power integrated over time. Power is the rate at which energy is transmitted. 5. Conversion: Energy: It can be converted from one form to another. Power: It cannot be converted from one form to another. 6. Unit: Energy: joules = watt-seconds or joule = Newton-meter Power: watt = joules/second 7. Various types of energy are kinetic, thermal, potential, gravitational, sound, electromagnetic, light, elastic, etc. Different kinds of power are electric power, optical power, human power, etc.
