Which formula represents the calculation for work?

Work is defined as the measure of energy transfer that occurs when an object is moved over a distance by an external force. The formula used to calculate work is given by the product of the force applied on the object and the distance over which that force is applied in the direction of the force. This relationship is captured in the formula W = Fd, where W represents work, F is the magnitude of the force applied, and d is the distance moved in the direction of the force.

It's essential to note that the formula captures the fundamental concept that work is only done when the force causes displacement. If there is no displacement (d = 0), regardless of the force applied, no work is done. The correctness of this formula is rooted in the definition of work in physics, emphasizing that both the direction of the force and the movement of the object are crucial in determining whether work is done.

Other formulas mentioned do not accurately encapsulate the concept of work in the context described. For instance, W = Fv would imply work is related to the velocity rather than the distance moved. W = F/a introduces acceleration into the equation, which is not directly relevant to the calculation of work. Lastly, W = mgh refers to the potential energy related
