Book excerpt: Relationship between mass and its movement or velocity, and its variation or acceleration in Global Dynamics. Laws of Newton. Concept of force, motion, energy and mass as properties of reticular matter. Types of movement. Dynamics of light and free fall bodies. Actually, Newton’s Physics provided the causes for being at rest more than those for motion. I don’t know if Newton liked to ski and eliminate friction much, but what he needed were forces that counteract the omnipresent force of gravity in order to explain why an object remained at rest. Wikipedia points out that while, according to the ancient Physics of the Greeks, the natural state of bodies was to be at rest, for Modern Physics, it is conserving the state of movement that they are in if the causes for being at rest, such as friction, are eliminated. If Newton’s Laws developed the dynamics of being at rest, the Theory of Relativity and Quantum Mechanics, both of which were around the beginning of the last century, have developed the kinematics of movement. That is, they are scientific theories that describe movement but not the causes for it, just its mathematical representation. Einstein’s General Relativity tries to add some causes, such as the geometric effect of the space-time continuum, but it is still a mathematical explanation, always biased and with many odd singularities.
