Gravity Theory Question?

Question

This is to settle an argument.
Who came up with the rule that if two objects are dropped from the same height in a vaccuum, they will fall at an equal rate of speed and hit the ground at the same time, regardless of weight difference.
I say it was Isaac Newton. Someone else says Galileo.
I'll need a web address for a page that will prove the correct answer.
Thanks!

Answer 1

gallileo.... one of the tests was done at the leaning tower of pisa, italy.

Contributions to Physics

His early studies, at the Univ. of Pisa, were in medicine, but he was soon drawn to mathematics and physics. It is said that at the age of 19, in the cathedral of Pisa, he timed the oscillations of a swinging lamp by means of his pulse beats and found the time for each swing to be the same, no matter what the amplitude of the oscillation, thus discovering the isochronal nature of the pendulum, which he verified by experiment. Galileo soon became known through his invention of a hydrostatic balance and his treatise on the center of gravity of solid bodies. While professor (1589—92) at the Univ. of Pisa, he initiated his experiments concerning the laws of bodies in motion, which brought results so contradictory to the accepted teachings of Aristotle that strong antagonism was aroused. He found that bodies do not fall with velocities proportional to their weights, but he did not arrive at the correct conclusion (that the velocity is proportional to time and independent of both weight and density) until perhaps 20 years later. The famous story in which Galileo is said to have dropped weights from the Leaning Tower of Pisa is apocryphal. The actual experiment was performed by Simon Stevin several years before Galileo's work. However, Galileo did find that the path of a projectile is a parabola, and he is credited with conclusions foreshadowing Newton's laws of motion.

Answer 2

rules are trouble-free truths that have exceeded by riggorous attempting out many times expressed mathematically, which includes F = Ma. A concept is built around a regulation and is greater complicated than a regulation. A concept has been subjected to extensive peer evaluate and regardless of many tries have not been disproved. What you're thinking of is a hypothesis. it is a testable concept it particularly is positioned out for peer evaluate. Now basically because of the fact something turns right into a concept or a regulation would not propose it can not be amended in time if new observations or evidence calls this form of regulation or concept into question. case in point in case you dropped a hammer and it fell as much as the ceiling, and this occurred on dissimilar activities, and could desire to be repeated by others, then the guidelines of action might decide for to be revised, however the flaws that make those rules so physically powerful is that there are not exceptions. that would not propose technology is the revelation of absolute reality by any ability (unquestionably revelation of absolute reality has greater to do with religious dogma than technology). There are some people who regrettably take care of technology like a faith and do a disservice to technology by assuming that medical theories are absolute truths, that's no much less incorrect than believing a medical concept is comparable to a hypothesis. we've purely to look on the evolution of present day atomic concept from 2 rules (the regulation of conservation of mass/potential and the regulation of sure proportions during the plum pudding sort, to the planetary sort to fashionable quantum sort. New discoveries are continually pushing forward the constraints of wisdom, technology is a techniques from static and there are a lot greater wonders interior the universe watching for discovery.

Answer 3

It was actually Galileo who was thought to have first tested the theory of objects falling at the same rate although this theory has been highly debated.

Answer 4

John Philoponus suggested this prior to Galileo's experiments with newton incorperating it into his 1st theory of motion.


I hate wikpedia but it was the first web page that came up!

Answer 5

Galileo demonstrated it experimentally by dropping two balls from the Leaning Tower of Pisa.

Answer 6

Issac newton discovered it an Galileo revealed it

Answer 7

The answer definitely is Galileo

Answer 8

On one of the Apollo missions it was demonstrated by an astronaut dropping a hammer and feather which indeed fell at the same rate.

Answer 9

it was galileo
