In science, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled.
23 wrz 2024 · Work, 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. The units in which work is expressed are the same as those for energy.
The scientific definition of work reveals its relationship to energy—whenever work is done, energy is transferred. For work, in the scientific sense, to be done, a force must be exerted and there must be motion or displacement in the direction of the force.
Learn how work is defined in physics as the transfer of energy by a force acting on an object as it is displaced. See examples, equations, and calculations of work in one-dimensional motion.
Work is the transfer of energy by a force acting on an object as it is displaced. The work W that a force F does on an object is the product of the magnitude F of the force, times the magnitude d of the displacement, times the cosine of the angle θ between them. In symbols, W = Fd cos θ.
