WebWork, Energy, and Power are three fundamental concepts of Physics. Work is defined as the displacement of an object when a force (push or pull) is applied to it. Energy is referred to as the ability to perform work. … WebHow to write the conservation of energy equation. The conservation of energy equation. K_0+U_0 + W_ {\text {NC}} = K+U K 0 + U 0 + W NC = K + U. is always true in any scenario. However, the conservation equation may look different depending on the problem because different forces and types of energy may be involved.
