In physics, values for work (and several other quantities) are almost always given in a unit of measurement called joules. One joule is defined as one newton of force exerted over one meter, or, in other words, one newton × meter.
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.
Total work done can be calculated with ease using this online work calculator for physics. It requires mass, initial velocity, and final velocity of the object to get the total work done.
