WebFuel consumption is measured in litres per km. (We also uses miles per gallon as a measure of performance – a high figure is good.) Larger vehicles, and those with a greater acceleration have more powerful engines, so that energy can be transferred more quickly from the fuel to do work. The work done = driving force × distance travelled. WebWork can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m).
