Power refers to the amount of work done by an object in a unit of time, that is, the power is a physical quantity that describes how fast the work is done. The amount of work is constant, and the shorter the time, the greater the power value. The formula for finding power is power = work / time. The power characterizes the physical quantity of the work. The work done in unit time is called power and is represented by P. Therefore, the power is equal to the scalar product of the force and the velocity of the force point of the object.
