the fifth major philosophical proposition in history: Galileo's gravity Experiment (Galileo's Gravity experiment)~in order to refute the theory that Aristotle's free falling velocity depended on the mass of the object, Galileo constructed a simple thought experiment. According to Aristotle, if a light object is tied to a heavy object and then dropped from the tower, the heavy object falls faster and the rope between the two objects is straightened. At this point the light object will cause a drag on the weight, which slows down the falling speed. However, on the other hand, when two objects are tied together, the mass should be larger than any single object, so the system should fall the fastest. This contradiction proves that Aristotle's theory is wrong. ~ Below is the Interpretation section ... This thought experiment helped to prove a very important theory: regardless of the mass of an object, the rate at which all objects fall freely is the same without regard to resistance.
