who discovered gravity?

Answer 1

Discovered?

Well, Isaac Newton is generally credited with writing a paper about it first, but it was around long before Newton.

Answer 2

Sir Issac newton discovered gravity,while he was sitting under an apple tree.

Answer 3

Galileo first deduced how falling bodies accelerated towards the ground. This predates Newton by a good 60 years. While he did not have a good answer on how mass was involved in the whole picture, he is the first to accurately get the value of g = 9.8m/s/s by experimental means. While Newton does have his concrete explaination of 'why' gravity is there, its discovery of 'how' goes to Galileo.

Answer 4

Sir Issac Newton defined the laws of gravity but egyptians or sumarians, one of the early civilizations understood that it happened.

Answer 5

A great English physicist and mathamatician Issac newton discoverd the law of gravity

Answer 6

Essac newton.i think u remember he was sitting under a tree when an apple falls n he discovered about gravity after it.

Answer 7

Since the time of the Greek philosopher Aristotle in the 4th century BC, there have been numerous attempts to understand and explain gravitation. Although these attempted explanations can not be called "scientific" in the modern sense of the word, they are nonetheless precursors of a scientific attitude towards natural phenomena. Aristotle believed that there was no effect without a cause, and therefore no motion without a force. He concluded that all things tried to move toward their proper place in the crystalline spheres of the heavens, and that bodies fell toward the center of the Earth in proportion to their weight. Another example of an attempted explanation is that of the Indian astronomer Brahmagupta who, in 628, wrote that "bodies fall towards the earth as it is in the nature of the earth to attract bodies, just as it is in the nature of water to flow". The Sanskrit term he used for gravity, 'gurutv-ākarshanam' (center-attraction), means "the pulling of weight".

In 1687 English mathematician Sir Isaac Newton published the famous Principia, which postulated the inverse-square law of universal gravitation. In his own words, "I deduced that the forces which keep the planets in their orbs must be reciprocally as the squares of their distances from the centers about which they revolve; and thereby compared the force requisite to keep the Moon in her orb with force of gravity at the surface of the Earth; and found them answer pretty nearly." Most modern non-relativistic gravitational calculations are based on Newton's work.

Newton's law of universal gravitation
Main article: Newton's law of universal gravitation
In 1687 Newton published his work on the universal law of gravity in his Mathematical Principles of Natural Philosophy. Newton’s law of gravitation states that: every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. If the particles have masses m1 and m2 and are separated by a distance r (from their centers of gravity), the magnitude of this gravitational force is:


where:

F is the magnitude of the gravitational force between the two point masses
G is the gravitational constant
m1 is the mass of the first point mass
m2 is the mass of the second point mass
r is the distance between the two point masses
To see the change in gravity on earth based on the altitude (r in the above equation) based on real examples, you can use the eXtreme High Altitude Calculator

example if you move the moon closer to earth by 1/2 you inverse it to make it 2 then sqaured the attaction between the eath and the moon is now 4 times stronger than it was at it normal distance
