Work and work-energy theorem a. Understand the definition of work so you can: 1). Calculate the work done by a specified constant force on a body that undergoes a specified displacement. 2). Relate the work done by a force to the area under the graph of force as a function of position, and calculate this work in the case where the force is a linear function of position. b.
