What is the formula for work done?

The formula for work done in physics is derived from the relationship between force and the distance over which that force is applied. Specifically, work is defined as the product of force applied to an object and the distance that the object moves in the direction of that force. Mathematically, this is expressed as:

Work = Force × Distance

In this context, force is measured in newtons and distance in meters, resulting in work measured in joules. This conceptual framework highlights that work is performed when a force causes displacement.

Option C, which states pressure times volume displaced, relates to work done in a specific thermodynamic context (such as pressure-volume work in gases), but it does not represent the general formula for mechanical work. The other options, energy times time and mass times acceleration, also do not align with the standard definition of work in physics. The correct understanding focuses on the direct relationship between force and displacement as the fundamental basis for calculating work done.
