In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity. Mechanical power is also described as the time derivative of work. In mechanics, the work done by a force F on an object that travels along a curve C is given b…

WebApr 10, 2024 · The definition of work is the power you apply to displace an object over a distance in a given time. Power is the energy you need to complete a given task. Formula. Total Work Done (W) = Power (P) x Time (t) or. Work = Displacement x Force. Power (P) =. Total Work Done (W)/Time (t) 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.

WebFormula for Power P = F × s/t As we know, Power = Work done upon time P = w/t Work = Force ( F ) × Displacement (s) P = F × s/t Here, P = Power. F = Force applied on the body.
