Free fall movement is the movement of an object released from a certain height in physics until it hits the ground. In history, Aristotle said that heavy objects would fall to the ground faster than light objects. People have also believed in this hypothesis for many years. Galileo, on the other hand, realized during his experiments that this was not the case Aristotle said. Two pieces of iron, one large and one smaller, released the ball from the Pisa tower and observed that both of them fell simultaneously.
