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. A force is said to do positive work if it has a component in the direction of the displacement of the point of application.
The formula for work is used to calculate work done in moving an object. Understand the work formula with Derivation, Examples, and FAQs.
Equation \ref{7.2} defines the total work as a line integral, or the limit of a sum of infinitesimal amounts of work. The physical concept of work is straightforward: you calculate the work for tiny displacements and add them up.
The general formula for work and for determining the amount of work that is done on an object is: W = F × D × cos (Θ) where W is the amount of work, F is the vector of force, D is the magnitude of displacement, and Θ is the angle between the vector of force and the vector of displacement.
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.
The formula for calculating work is Work = Force × Distance. Hence, to calculate the distance from force and work, proceed as follows: Determine the work done, W, when the force, F, is applied. Divide the work done, W, by the applied force, F. Congrats, you have calculated the distance from the force and work!
Evaluate the work done for various forces. In physics, work is done on an object when energy is transferred to the object. In other words, work is done when a force acts on something that undergoes a displacement from one position to another.
