WHAT IS GALILEO'S EXPERIMENT LIKE?

Will larger objects cause faster things to light on the surface of the Earth? Maybe for a clear answer to this question is "no"........................

Why? Because at school we are taught that the acceleration of gravity is the same for all objects so that the acceleration of falling objects that fall freely does not depend on their mass. So, if 1 kg of rice and 10 kg of rice are dropped from the same height, it should reach the ground at the same time. The statement that in fact has been proven true by Galileo's experiment.

By the way, what is Galileo's experiment like? Did he go up to the Tower of Pisa, then drop things that were different in weight? Apparently not so! Besides gravity, air friction and many factors also affect the falling motion of objects. For example, it could be that iron falls faster than cotton.

The Italian scientist Galileo Galilei (then professor of mathematics at the University of Pisa) is said to have dropped two spheres of different masses from the Leaning Tower of Pisa to demonstrate that their time of descent was independent of their mass, according to a biography by Galileo's pupil Vincenzo Viviani, composed in 1654 and published in.

Historical records show Galileo did not actually conduct experiments directly in the Tower of Pisa. The majority of historians believe that the story of the experiment in the Pisa Tower was just an illustration that was told by word of mouth.

At the time when Viviani asserts that the experiment took place, Galileo had not yet formulated the final version of his law of free fall. He had, however, formulated an earlier version which predicted that bodies of the same material falling through the same medium would fall at the same speed. Galileo set out his ideas about falling bodies, and about projectiles in general, in his book Two New Sciences. The two were the science of motion, which became the foundation-stone of physics, and the science of materials and construction, an important contribution to engineering. Galileo arrived at his hypothesis by a famous thought experiment outlined in his book On Motion. Galileo's experiment: Wikipedia source

Then, what kind of Galileo's experiments succeeded in refuting the old idea that heavy objects (larger masses) would fall faster than light objects? Keep in mind, actually Galileo did not conduct experiments directly.

He does what in English is called "thought experiment", which can be translated into Indonesian as "thought experiment". He did experiments only in the head and with that thought experiment he was able to refute old thinking.

First of all, Galileo thought that if there were two things with different masses, according to the old assumption, heavier objects would fall faster than light ones.

When we join the two objects into a unity with a rope that is ignored by mass, heavier objects can attract lighter objects so that light objects will fall faster than if they were alone.

Meanwhile, heavier objects can also be inhibited by light objects that will move more slowly than if they fall alone. Thus, collecting the two objects will be more dangerous than objects that fall and are faster than if light objects fall on their own.

In fact, the objects produced from the object are clearly heavier than each object. Supposedly, according to a long time, the combination of objects will fall faster than the two objects.

How is it possible that with the old assumption that was "considered right" there were two different results? Therefore, Galileo concluded that the old assumption that said heavy objects would fall faster than light objects was a false assumption.

The correct result is only obtained if it is assumed that a heavy object (a larger mass) will fall along with a light object. That is, whether it is a heavy object, a light object, or a combination of both objects will fall at the same time when dropped from the same height.
