By observing the return times of the pulses, scientists have confirmed that the moon and Earth fall or accelerate towards the sun at the same rate — to the precision of 1. The experiment galiileo described in Simon Stevin’s book De Gallieo der Weeghconst The Principles of Staticspublished in and a landmark book on statics:.
Imagine two objects, gallileo light and one heavier than the other one, are connected to each other by a string. History of Western Philosophy. Views Read Edit View history. Now lets place the same box with the same objects in outer space, far away from any gravitational field.
Astronaut David Scott performed a version of the experiment on the moon during the Apollo 15 mission indropping a feather and a hammer from his hands.

Asimov’s Biographical Encyclopedia of Science and Technology. The name of the experiment is Lunar Ranging Experiment.

But Galileo was different. Einstein noted that if a person falls in a gravitational field and only observes objects around him, he would think that he is weightless ie aristole not experience any gravitational field.

If the rate of fall of the earth and moon was different, it ths have shown in the results of this experiment as deviations in trajectory and therefore distance between Earth and the moon.
Because of the negligible lunar atmosphere, there was no drag on the feather, which hit the ground at the same time as the hammer. 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.
According to the story, Galileo discovered through this experiment aristot,e the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle ‘s theory of gravity which states that objects fall at speed proportional to their mass. And this is how it was done: Between —92, thee 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 Vivianicomposed in aristotlee published in Now some historians doubt whether this experiment actually took place.

EdwardsWilliam A. This is a nice thought experiment but the ultimate test of all science is experiment.
Galileo’s Leaning Tower of Pisa experiment
Each pulse lasts pico seconds and such laser pulses are sent 10 times each second. This article has no associated abstract. Aristotle believed that if two objects, one heavier and the other lighter were dropped together, the heavier one will fall faster and therefore reach the ground first. Most historians consider it to have been a thought experiment rather than a physical test. Edwards – – Erkenntnis 40 2: An Unpublished Letter of Galileo to Peiresc. So the experiment is done on a massive scale.
pisaa Patterns of Argumentation in Galileo’sDiscorsi. This contradiction leads one to conclude the assumption is false. Galileo arrived at his hypothesis by a famous thought experiment outlined in his book On Motion. Setting the record straight”. Therefore all bodies fall at the same rate irrespective of their weights.
