Unformatted text preview: W net = F net ( x f x o ) Using Newton's Second Law we can substitute for F: W net = ma ( x f x o ) Given uniform acceleration, v f 2 v I 2 = 2 a ( x f x o ) . Substituting for a ( x f x o ) into our work equation, we find that: W net = mv f 2 mv o 2 This equation is one form of the workenergy equation, and gives us a direct relation between the net work done on a particle and that particle's velocity. Given an initial velocity and the amount of work done on a particle, we can calculate the final velocity. This is important for calculations within kinematics, but is even more important for the study of energy, which we shall see below....
