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.

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.

2024年12月11日 · 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.

2023年7月19日 · In physics, “W” represents work, which is a measure of energy transfer that occurs when an external force is applied to an object, causing it to move over a certain distance. For work to be done, the force must have a component applied in the direction of …

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.

2024年3月12日 · 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 parallel to the motion, times the magnitude \(d\) of …

2020年12月28日 · The definition of work in physics is force times displacement. It is a scalar produced by two vectors. The angle between the force and the displacement is also factored in. Work has units of energy called joules in SI units. The work-energy theorem relates kinetic energy to net work in a system.

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 \(\theta\) between them. In symbols, \[W = Fd \, \cos \, \theta.

2019年4月23日 · 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.
