WebIn physics, the term work has a very specific definition. Work is application of force, f, to move an object over a distance, d, in the direction that the force is applied. Work, W, is described by the equation W = f d. Some things that we typically consider to be work are not work in the scientific sense of the term. Let’s consider a few examples. WebApr 5, 2024 · P = W t. Power is the rate at which energy (heat and electrical) is transferred. While studying electricity, you would find the power is defined as: Power = V * I, where V is the voltage within the circuit, and I is the current through the circuit. We could derive another formula for power from the formula for work.
