The Work-Energy Theorem states that the net work done on an object in going from position \(A\) to position \(B\) is equal to the object’s change in kinetic energy: \[\begin{aligned} W^{net}&=\frac{1}...The Work-Energy Theorem states that the net work done on an object in going from position \(A\) to position \(B\) is equal to the object’s change in kinetic energy: \[\begin{aligned} W^{net}&=\frac{1}{2}mv_B^2-\frac{1}{2}mv_A^2=\Delta K\end{aligned}\] We can thus write that the total work done by non conservative forces is equal to the change in potential and kinetic energies: \[\begin{aligned} W^{NC}=\Delta K+\Delta U\end{aligned}\] In particular, if no non-conservative forces do work on an ob…
