For example both V ⋅ s and V s are acceptable. Thus, SI authority does not encourage anyone to use this unit. Following is the table of units and dimensional formula: Some commonly used work units also include erg in the CGS system, the horsepower-hour, the newton-metre, the foot-pound, the kilowatt-hour, the foot-poundal, and the litre-atmosphere. In physics, work is the energy transferred to or from an object via the application of force along a displacement. When a compound unit SI unit symbols is made by multiplying two or more other units, its overall symbol should consist of the symbols for the separate units joined by dots which are raised, i.e. ⋅ . A force is said to do positive work if (when applied) it has a component in the direction of the displacement of the point of application. kg. The SI unit of work is joule (J).
