A joule is the SI unit of energy, representing the amount of work done when a force of one newton is applied over a meter, while an erg is a much smaller unit, used in the CGS system, equal to 10^-7 joules.

Mentor's note: Moved from HW for a better fit Homework Statement:: A joule is defined as "the energy transferred to an object when a force of one Newton acts on that object in the direction of its motion through a distance of one meter." Explain this definition. Relevant Equations:: 1J...
1.A unit of work or energy transfer. One joule is equal to work done by a force of one newton moved about 1 m in the direction of the force. 2.(J) A unit of energy equal to the work done when a force of one newton is applied through a distance of one meter. Used instead of...
joule, unit ofworkorenergyin theInternational System of Units(SI); it is equal to the workdoneby aforceof onenewtonacting through onemetre. Named in honour of the English physicistJames Prescott Joule, it equals 107ergs, or approximately 0.7377 foot-pounds. In electrical terms, the joule equa...
