A Forgotten Controversy in Basic Classical Mechanics: The Difference between the Energy Equation and the Center - of - Mass Equation

  • Aria Bozorgmehr physics researcher

Abstract

In this paper we indicate the difference between energy equation and the center of mass equation by an especially example. According to our opinion, in teaching mechanics, we should more clearly an integral of Newton's second law and the energy equation. Maybe this leads to greater clarity in the notions of system, work and energy.
