WebSep 7, 2024 · Dans le domaine de l’énergie électrique, un joule (J) est l’énergie donnée par une puissance de 1 watt pendant une seconde Soit le travail produit par une force de 1 newton dont le point d’application se déplace de 1 mètre dans la direction de la force L’unité doit son nom au physicien anglais James Prescott joule WebWhenever a new quantity is introduced in physics, the standard metric units associated with that quantity are discussed. In the case of work (and also energy), the standard metric unit is the Joule (abbreviated J). One Joule is equivalent to one Newton of force causing a displacement of one meter. In other words, The Joule is the unit of work.
WebJul 16, 2024 · Work and energy have the same units. From the definition of work, we see that those units are force times distance. Thus, in SI units, work and energy are measured in newton-meters. A newton-meter is given the special name joule (J), and \(1 \, J = 1 \, N \cdot m = 1 \, kg \, m^2/s^2\). One joule is not a large amount of energy; it would lift a ... WebFigure 1.
