    Power is the rate with respect to time at which work is done; it is the time derivative of work: =, where P is power, W is work, and t is time. We will now show that the mechanical power generated by a force F on a body moving at the velocity v can be expressed as the product: P = d W d t = F ⋅ v {\displaystyle P={\frac {dW}{dt}}=\mathbf {F ...

    Power can be expressed in units of watts (W). This unit can be used to measure power related to any form of energy or work. You have most likely heard the term used in relation to electrical devices, especially light bulbs. Multiplying power by time gives the amount of energy.

    Feb 20, 2022 · Power is the rate at which work is done, or in equation form, for the average power \ (P\) for work \ (W\) done over a time \ (t\), \ (P = W/t\). The SI unit for power is the watt (W), where \ (1 \space W ….

    We express the relation between work done and the time interval involved in doing it, by introducing the concept of power. Since work can vary as a function of time, we first define average power as the work done during a time interval, divided by the interval, Pave = ΔW Δt. P ave = Δ W Δ t.

    Power = ft lb/s= hp. The rate of doing work is equal to the rate of using energy since the a force transfers one unit of energy when it does one unit of work. A horsepower is equal to 550 ft lb/s, and a kilowatt is 1000 watts. 1 hp = 745.8 watts.
