Therefore, work is equal to force multiplied by distance: W=Fd W = F d. Because force is a component of work and an impact is the conversion of energy into work, you can use the equations for energy and work to solve for the force of an impact. The distance traveled when the work is accomplished by an impact is called the stop distance.
