Foot-pound (energy) Foot-pound (energy) The foot pound-force (symbol: ft⋅lbf or ft⋅lb) is a unit of work or energy in the Engineering and Gravitational Systems in United States customary and imperial units of measure. It is the energy transferred upon applying a force of one pound-force (lbf) through a linear displacement of one foot. The corresponding SI unit is the joule. The foot-pound is often used to specify the muzzle energy of a bullet in small arms ballistics, particularly in the United States. "Foot-pound" is also used as a unit of torque (see "pound-foot (torque)"). In the United States this unit is often
Energy (esotericism) 18th and 19th centuries with Mesmer and the magnetism. They continued to be discussed in the 20th century by some thinkers and practitioners in the modern New Age movement. As biologists studied embryology and developmental biology, particularly before the discovery of genes, a variety of organisational forces were posited to account for their observations. German biologist Hans Driesch (1867–1941), proposed entelechy, an energy which he believed controlled organic processes. However such ideas are discredited and modern science has all but abandoned the attempt to associate additional energetic properties with life. According to Brian Dunning, the scientific term energy is, in
