What experiment did Newton do to find that gravity existed?

Answer 1

He didn't do an experiment, but he did study experiments on falling bodies and projectiles done by Galileo. See the source.

Answer 2

In his Hypothesis of Light of 1675, Newton posited the existence of the ether to transmit forces between particles. The contact with the theosophist Henry More, revived his interest in alchemy. He replaced the ether with occult forces based on Hermetic ideas of attraction and repulsion between particles. John Maynard Keynes, who acquired many of Newton's writings on alchemy, stated that "Newton was not the first of the age of reason: he was the last of the magicians."[5] Newton's interest in alchemy cannot be isolated from his contributions to science.[6] (This was at a time when there was no clear distinction between alchemy and science.) Had he not relied on the occult idea of action at a distance, across a vacuum, he might not have developed his theory of gravity. (See also Isaac Newton's occult studies.)

Answer 3

nicely, the apple tale is complete nonsense. And Newton grow to be on no account Galileo's modern - Galileo died interior the January of the year Newton grow to be born. Newton grow to be certainly attempting to come back to a determination the question of what keeps the planets and the moon in orbit. His assistant claims that he mused over an apple tree in his mom's backyard and regarded no count number if the comparable tension that pulled an apple to the earth if it fell would desire to be responsible. there is not any checklist that any apple fell everywhere, least of all on his head. however the experimental verificationof his theory got here in his setting up the orbital action of the moon to the belief.

Answer 4

I don't think he did any experiments, except in his head, for gravity. He used the data gathered by other scientists for this, people such as Descartes, Huygens, Hooke, Kepler, Halley, and Wren (and many others).

The story about the apple -- even if it was true, it was not really an experiment. It was more of an inspiration.

Answer 5

There wasn't one.

Anyone who has even fallen over is aware of gravity.

The story goes an apple fell on his head but I think he said he just observed one falling and that got him thinking about the mechanics of gravity.

He didn't need to know it existed.
