Mechanical work is done when a force f displaces an object by a distance d: (1) w = f × d. The basic unit of energy is the joule. One joule is the amount of work done when a force of 1 newton acts over a distance of 1 m; thus 1 J = 1 N-m. dakota county minnesota district courtWebPerson as author : Pontier, L.
