In the straightforward cases where a constant force moves an object at constant velocity, the power is just P = Fv. In a more general case where the velocity is not. Power Force AG importiert und distribuiert Produkte für den Schweizer Detailhandel. What's the difference between Force and Power? The concepts of force and power seem to convey similar meanings and are often confused for each other.
Power from force - Sie
Examples of direct contact forces include the friction of car tires on a road, or the air resistance on a moving car. Therefore, the car developed an average of 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. In mechanics , the work done by a force F on an object that travels along a curve C is given by the line integral:. In the case of constant power P , the amount of work performed during a period of duration T is given by:. A car engine is an example of a machine that is given a power rating.
