Let’s put the Work Kinetic Energy Theorem to good use… W tot = ΔKE F d Suppose there is a forceF acting on a mass m moving with velocity v o (not shown, to the right) in deep space. Let that force act over a displacement d. 2 As always, sketch all of the following proble...
Work-Energy Theorem Examples Lesson Summary Frequently Asked Questions What is the work-energy theorem equation? The work-energy theorem equation is W = ?KE where W is work and ?KE is change in kinetic energy or the difference between the final kinetic energy and the initial kinetic energy ...
Here the work-energy theorem can be used, because we have just calculated the net work, Wnet, and the initial kinetic energy, 12mv2012mv02. These calculations allow us to find the final kinetic energy, 12mv212mv2, and thus the final speed v. Solution The work-energy theorem in equation...

Well, here we will discuss the work-energy theorem, limitations, and work-energy theorem examples. To complete the work, energy is needed, and hence in this theorem, we will know the relation between energy and work. Work relates to displacement, and displacement relates to kinetic energy. Th...
We analyse two additional examples in order to ilustrate the subtle aspect of Newtonian theory: despite something is said about where the work is going to, namely the Work - Kinetic Energy Theorem, absolutely nothing is said about where the work comes from (we explain in ou...
