Power in mechanical systems is the combination of forces and movement. 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 by … Webpower = force × velocity e.g. power = work done time taken power = force × distance (in direction of the force) time taken, so power = force × velocity. (However, this only works if …
