The Main Idea
Work perhaps is a term that most of the people are commonly exposed to. People often use the term "work" to describe their jobs, the amount of energy they had to input to get something done, or even when they describe their gym and their routine exercise. To physicists however, work has a rather specific definition. In physics, work refers to the "efficiency" of the force. A force is doing "work" when acting upon a matter or a particle if it causes the matter to move or change in displacement. 
For some people, the new rather absurd concept of work may be a bit confusing. It is important to take consider of the three so called "ingredients" when determining work. Those ingredients are the force, displacement and a cause. The force must "cause" the change in displacement in order to be doing work.
A Mathematical Model
What are the mathematical equations that allow us to model this topic. For example [math]\displaystyle{ {\frac{d\vec{p}}{dt}}_{system} = \vec{F}_{net} }[/math] where p is the momentum of the system and F is the net force from the surroundings.
