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...
is your chance to take on “the big one”: to investigate the validity of the work-energy theorem. Theory: If an amount of work, W, is done on a system, then the kinetic energy, K, of the system changes. The change in the kinetic energy is equal to the amount of work done. Sta...
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...
