WebIt acts over a distance of 20 m, in the same direction as the displacement of the object, implying that the total work done by the force is given by W = Fx = (50) (20) = 1000 Joules. … WebConclusions. Work is the energy required to move something against a force. The energy of a system can change due to work and other forms of energy transfer such as heat. Gases do expansion or compression work following the equation: work = − P Δ V. \text {work} = -\text P\Delta \text V work = −PΔV.
