\nIf the net work done on a moving object is positive, its kinetic energy increases.
\n<\/section>\n
\nThis is directly explained by the Work-Energy Theorem, which states that the net work (W_net) done on an object by external forces is equal to the change in its kinetic energy (\u0394KE): W_net = \u0394KE = KE_final – KE_initial. If W_net is positive, then \u0394KE must be positive, meaning KE_final > KE_initial. Therefore, the kinetic energy increases.
\n<\/section>\n
\nConversely, if the net work done is negative, the kinetic energy decreases. If the net work done is zero, the kinetic energy remains constant (although the velocity vector might change direction, the speed and thus KE remain the same).
