That is, if you know the speed at the start of the path, vA, and the speed at the end of the path, vB, then the net work done on the object along the path between A and B is given by...That is, if you know the speed at the start of the path, vA, and the speed at the end of the path, vB, then the net work done on the object along the path between A and B is given by: Although we introduced the kinetic energy as a way to calculate the integral for the net work, if you know the value of the net work done on an object, then the Work-Energy Theorem can be used to calculate the change in speed of the object.
