EnergyEnergy is the ability to do work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Units of Energy: The SI unit of energy is the joule (J) or newton-meter (N * m). The joule is also the SI unit of work. may be defined as the capacity or ability to do work. Energy exists in everybody whether they are human beings or animals or non-living things. Energy is measured in the same unit as work, that is, JoulesJoule is the SI (International System of Units) unit of energy and work. It is equal to the amount of work done when a force of 1 newton displaces a mass through a distance of 1 metre in the direction of the force applied. Formula:Work done = Force applied × Distance travelled in the direction of the forceWork done (W) = Force (F) × Distance (D)W = F × D work, W is measured in joules (J)force, F is measured....
