1. How to understand the power
refers to how much power the work done by the object per unit time, i.e., the speed of power is described physical work. A certain number of power, the shorter the time, the greater the power value. The formula for the power demand power = work / time. How quickly characterization of power for power’s physical. The work done per unit time is called power, with P. Therefore, power is equal to the product of the urging force of the object the force point speed.
