Galileo may have a better publicity agents, but he was not the first.
Philoponus refuted Aristotle's statements and emphasized that experience shows that "if one lets fall simultaneously from the same height two bodies differing greatly in weight, one will find that the ratio of their times of motion does not correspond to the ratio of their weights, but that the difference in time is a very small one" (In Physica, 683, 17).
Also, in 1544, Benedetto Varchi published a statement that Aristotle was wrong about falling bodies.
Dutch Simon Stevin repeated this in 1584.
Whoever he was, he fell directly into well-deserved oblivion, and his name isno longer mentioned. The reason for that is simply that he was wrong. Therate at which an object falls is not related to its mass.
The first recorded experiment to verify this was Galileo. In 1542, a century before Galileo, Bendetto Varchi published experimental results showing this to be true.
anything that is real takes up space and has mass. that is how and object is related to mass
Fg is equal to mass times acceleration. While the mass of the object does not change, acceleration (gravity) increases the more the object falls to the ground.
wind resistance, and gravity, mass does not in any way contribute to how an object falls.
-- the mass of the object -- the height through which it falls
By the mass of every object
What energy is related to the mass and speed of an object
Because gravity is the sorce of how the object with less mass falls down
By the mass of every object
it means that you found the mass of an object.
The more mass it has, the faster it will fall and vice versa.
