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 Work–Energy Theorem. In physics, the term work has a very specific definition. Work is application of force, f f, to move an object over a distance, d, in the direction that the force is applied. Work, W, is described by the equation
In physics, work represents a type of energy. Work is done when a force acts on something that undergoes a displacement from one position to another. Forces can vary as a function of position, and displacements can be along various paths between two points.
Learn the scientific definition of work as the product of force and displacement, and how it relates to energy. Find out the factors that affect work, such as force, displacement and angle, and the unit of work in joules.
Learn how work is a measure of energy transfer using force and displacement, and how to calculate it with a simple formula. Explore the history, types, and units of work in physics, and see examples and FAQs.
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.
