Derivation of conservation of energy class 9

WebOct 3, 2024 · 1. Work done by a constant force. Work done by a force acting on an object is equal to the magnitude of the force multiplied by the distance moved in the direction of the force. Work done = force x displacement. Work done has only magnitude and no direction i.e., work is a scalar quantity. SI unit of work is joule (J).
