Work and Kinetic Energy

Authors: M. R. Carvajal

We point to a problem with the current generally accepted idea that work W = ∫ F⋅dx transfers kinetic energy KE = (1/2)mv2, showing that with exactly the same amount of work, done through a pulley or a lever, different amounts of kinetic energy can be imparted to objects of different masses. We do this without violating the laws of classical mechanics, or the work-kinetic energy theorem W = ΔKE.
