"WebThe work-energy theorem states that the total work done from external forces on a body is equal to the change of kinetic energy. However, the change in kinetic energy must also include the translational kinetic energy ‘TKe’ and the rotational kinetic energy ‘RKe’. In the formula below, W is work, and ΔKe is the change in kinetic energy. " - Kinetic energy work theorem
