The concept of force and the formalization of non-quantum-mechanical theories

  • Nicholas Ionescu-Pallas
  • Liviu Sofonea


The paper deals with the role of the concept of force in different classical mechanical and field theories, pointing out the existence in all cases of a Lorentz-type expression for force. In the case of the classical theory of the gravitational field we obtain the same Lorentz-type expression.
