Did newton actually discover gravity?
Isaac Newton did not discover gravity, as objects had been falling towards the Earth long before him. However, Newton was the first to mathematically describe gravity through his Universal Law of Gravitation, which explained how objects are attracted to each other based on their masses and distances.
Did Einstein discover gravity?
No GaleleoAdditional answerNobody discovered gravity. Everyone in the world has always been under the influence of gravity, but never thought about it. Newton was the first person to do so.And Galileo did not discover gravity. What he did was to show that two objects of different weights would accelerate under gravity at the same rate. He dropped two objects from the Leaning Tower of Pisa to prove it.
Had anyone heard of gravity before newton introduced it?
Gravity was discovered long before Newton was around. Newton just postulated gravities relationships with acceleration and mass.
How did newton's work on orbit add to the work Kepler had done?
Kepler made discoveries regarding the planet's distance from the sun and how long it takes a planet to orbit the sun. In Newton's Version of Kepler's Third Law, Newton expands on these ideas by using his Theory of Gravity.
What did Sir Isaac Newton discover after he discovered gravity?
After discovering gravity, Sir Isaac Newton went on to develop his laws of motion, which describe the relationship between an object's motion and the forces acting on it. He also made significant contributions to mathematics, optics, and the study of light and color through his work on the nature of light and the invention of the reflecting telescope.
When did Isaac Newton discover Newtons?
Even before Sir Isaac Newton was born, roughly 8 out of every 23 people had already noticed that when they jumped out of bed, their feet went to the floor, and that when they dropped something, it fell to the ground. Gravity was already quite universally known, whether or not that's what anybody called it, and it didn't need to be discovered. All Newton did was to accurately describe how it works. He published his explanation in 1690. But Newton's breakthrough was to realise that gravity is not just that well known constant force that gives people their weight, but it also acts between the Sun and the planets. The force between two objects is proportional to their masses and inversely to the square of the distance between them. Nobody jumping out of bed could ever have worked that one out. What the discovery allowed Newton to do was to explain how the planets move in elliptical orbits under the force of gravity, all the details. It allowed the mass of the Sun and planets to be calculated and it confirmed that the planets all move in stable orbits so that we don't have to worry about falling into the Sun ever - not for a couple billion years anyway.
Did it take long for sir Issac newton to develop the laws of motion and gravity?
Isaac Newton developed his laws of motion and theory of gravity over a period of several years, with the work culminating in the publication of his famous work "Philosophiæ Naturalis Principia Mathematica" in 1687. The process involved extensive experimentation, observation, and mathematical analysis.
How earth get the gravitational force?
Everyone knew all about gravity on Earth for as long as people knew about anything, but it took Newton to realize that this same force is what keeps the Moon in orbit around the Earth and the planets around the Sun, and was responsible for the tides. Einstein's (and Newton's) theory have as central features that mass (and energy in Einstein's model) create the effects of gravity, but do not explain (as far as I know) why this must be the case, and why there are not other sources of gravity.

Why is it incorrect to say that newton discovered gravity?
The fact that objects fall towards the surface of our Earth is something known not only to humans long before Newton, but (in can be argued) by animals for 100s of millions before the first humanoid had a thought. Newton showed that the fall of an object on the surface of our Earth, AND the orbit of planets around our Sun, are the result of one and the same phenomena. In other words, the law of gravity applies equally outside our planet as it does on our planet.
What did Galileo ideas to do with the law of gravity?
Very little. It wasn't until Kepler that the relation between orbital period and the length of the axis of the orbit was found, and it wasn't until Newton that these relations could be derived from Newton's law of universal gravitation. Newton published his findings long after Galileo died.
How long did Isaac newton live in Woolsthorpe?
Isaac Newton lived in Woolsthorpe for approximately two years, from 1665 to 1667. During this time, he conducted a significant amount of research and experiments, including his work on gravity and calculus.
