1, the formula of work: w = fs When an object is lifted very high, w = ghw = pt.

2. power formula: p = w/TP = w/t = fs/t = Fv (v = p/f)

3. Useful work formula: W has = GH level W has = =FsW has = W total -W amount.

4. Total work formula: wtotal = fs (s = NH) wtotal = wtotal/η wtotal = wtotal+wtotal = Ptotal T.

Work, also called mechanical work, is a physical quantity that indicates the spatial accumulation of force acting on an object in physics. Work is a scalar, and its magnitude is equal to the product of the force and the distance the object moves in the direction of the force. The international system of units is joule. The word "work" was originally coined by the French mathematician Jasper gustav Coriolis.
