Webwork, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. If the force is constant, work may be computed by multiplying the length of the path by the component of the force acting along the path. WebFrom 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 ⋅ m = 1 kg ⋅ m 2 /s 2 1 J = 1 N ⋅ m = 1 kg ⋅ m 2 /s 2. One joule is not a large amount of energy; it would lift a small 100 ...

WebDec 25, 2024 · Is work a force acting over a distance? In words: Work is equal to the force that is exerted times the distance over which it is exerted. In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph.
