In wheel and belt systems, the primary function is not to act as energy multipliers. Instead, these systems primarily function to transmit motion and forces. Force multipliers and distance multipliers both describe how these mechanisms enhance the effects of applied forces or enable the movement of objects over greater distances, respectively.

Force multipliers allow a smaller input force to generate a larger output force through mechanical advantage, while distance multipliers focus on allowing an object to travel a larger distance with a corresponding motion. Additionally, wheel and belt systems convert rotational motion into linear motion, which is another essential characteristic of their function.

While energy is conserved in mechanical systems according to the principles of physics, meaning that energy does not increase as it is transformed or transferred in a wheel and belt setup, these systems do not inherently multiply energy. Therefore, saying they act as energy multipliers is an inaccurate description of their function.
