These distinct forces are going to be discussed in more depth later on in Lesson two together with in other classes.}
Galileo Galilei was the very first to point out the inherent contradictions contained in Aristotle's description of forces. Dynamic equilibrium was initial described by Galileo who seen that specified assumptions of Aristotelian physics ended up contradicted by observations and logic. Galileo recognized that easy velocity addition needs the notion of an "absolute rest body" did not exist. Galileo concluded that motion in a constant velocity was totally reminiscent of relaxation. This was Opposite to Aristotle's notion of a "organic state" of rest that objects with mass Normally approached. Easy experiments confirmed that Galileo's idea of the equivalence of frequent velocity and relaxation had been right.

Some astrophysicists predicted the existence of an undiscovered planet (Vulcan) that may demonstrate the discrepancies. When Einstein formulated his idea of standard relativity (GR) he focused on Mercury's problematic orbit and located that his concept additional a correction, which could account for the discrepancy.
