This 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 (ΔKE): W_net = ΔKE = KE_final - KE_initial. If W_net is positive, then ΔKE must be positive, meaning KE_final > KE_initial. Therefore, the kinetic energy increases.
How is the kinetic energy of a moving object affected if the net work done on it is positive ?
