WebPractical examples of energy measurement using joules include the energy required to lift objects, the energy released when objects fall, the heat required to raise temperature, and the kinetic energy of moving objects. One of the dimensional representations of a joule is the N·m (Newton-meter), which is equivalent to the SI unit for torque. WebApr 10, 2024 · Power is the rate at which energy is transferred or Converted or the rate of doing work. SI Unit of power is Watt; 1 Watt = 1 J/s = 1 kg -m 2 /s 3. 1 watt is equal to 1 joule of work done in 1 second. Watt is named after the famous inventor James Watt. Watt is a scalar quantity, which means it doesn’t contain direction.
