Energy has the same units as work: a force applied through a given distance. For example, the SI unit of energy – the joule – equals one Newton applied through a distance of one metre. Lord Kelvin amalgamated previous laws into Laws of Thermodynamics. Energy is neither created nor destroyed, but only transferred from one place or one form to another. Kinetic energy may represent the amount of work that accelerates a body to a given velocity; gravitational potential energy may constitute the amount of work that elevates or moves a mass against a gravitational pull. Biological chemical processes involve molecular biology and biochemistry, and ...
