Work, measured in joules, increases kinetic energy when force aligns with motion, as seen when pushing a box. Work also transfers energy to potential forms, such as gravitational potential energy in lifting objects or spring potential energy when stretching a spring. These examples illustrate how work drives energy changes in systems.

The work done is equal to the product of the force and the distance through which the force acts. Work is measured in SI units in joules (J), named for the English physicist James Joule: Although work is always the product of force and distance, there are simpler expressions if the force is constant or in the direction of motion.

The physics definition of “work” is a bit different from the everyday one, simply holding something up does not involve work no matter how heavy it is. It is only when you drop it that work (by gravity) is being done.

In pumping problems, the force required to lift the water to the top of the tank is the force required to overcome gravity, so it is equal to the weight of the water.

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. We first define the increment of work dW done by a force acting through an infinitesimal displacement as the dot product of these two vectors. Then, we can add up the contributions for infinitesimal displacements, along a path between two po

(Then positive x corresponds to a stretch and negative x to a compression.) With this choice of coordinates, the spring force has only an x-component, F x = −kx, and the work done when x changes from x A to x B is
