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.
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.
Lesson 1: Work and energy. What are energy and work? What is kinetic energy? What is gravitational potential energy? What is conservation of energy? Work and the work-energy principle. Work as the transfer of energy. Work example problems. Work as area under curve. Thermal energy from friction. What is thermal energy? Conservative forces. Power.
Work is the product of the component of the force in the direction of the displacement and the magnitude of this displacement. Learn the factors on which work depends along with its formula, unit, and definition.
Work, \(W\), is a transfer of energy from one physical system to another via a force acting between the two through a distance. Only the part of the force that acts parallel to the displacement contributes to work.
In physics, “work” is a measure of the energy transferred to or from an object using a force acting on the object as it moves through a distance. It’s important to understand that work is only done when a force causes displacement or movement in the direction of the force applied.
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.
In physics, work is defined as a force causing the movement—or displacement—of an object. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force.
