Webb10 apr. 2024 · The work equations or work formulas is articulated as: W = F d Cos θ. In the above work equation. W = Amount of work. F = Vector of force. D = Magnitude of displacement. θ = Angle between the vector of force and vector of displacement. The SI unit of work is joules and its dimensions are kg.m²/s². WebbThe maximum amount of work one can attain from heat is given by the Carnot efficiency. Heat is the energy associated with the random motion of particles, while work is the energy of ordered motion in one direction. Therefore heat is "low-quality" energy and work is "high-quality" energy, and this supports the entropy statement of the Second Law.
