Question
The SI unit of mechanical energy
isSolution
Mechanical energy is the sum of kinetic and potential energies, and both are measured in Joules (J). A Joule is defined as the work done when a force of 1 Newton displaces an object by 1 meter in the direction of the force.
- Watt is the unit of power.
- Newton-second is the unit of momentum.
- Joule-second relates to Planck's constant but is not used for mechanical energy.
