How did Galileo galilei inspire Isaac newton?

Answer 1

Copernicus put forward a new theory of the planets that put the Sun at the centre, with the Earth orbiting round it just like all the other five known planets. This challenged the old Ptolemaic system and it also challenged the church's teaching, which worried Copernicus and his book 'De Revolutionibus' was not published until the year he died, 1543.
Galielo took up the Copernican theory after observing the moons of Jupiter and the phases of Venus with his telescope, which he believed showed a fault in the Ptolemaic system. He started a dispute about the Copernican system with the catholic church authorities, and was eventually forced to recant for lack of enough proper evidence supporting it at that time.
Kepler took part of the Copernican system, the part that puts the Sun at the centre, and produced a new model based on observations made by Tycho Brahe with unprecedented accuracy. The planets were now in elliptical orbits following Kepler's three laws, published in 1609. These were based entirely on observations and he had no idea why the planets followed his laws.
In 1687 Newton had done a lot of theoretical work and published his famous 'Principia' in which he described the laws of motion and the newly discovered differential calculus, as well as the inverse-square law of gravity. He was able to use these to show by detailed mathematics that an object in orbit round a massive object, under the force of gravity, must follow an elliptical orbit, with the massive object at one focus, just as Kepler had found for the planets.

So the main line of development goes from Copernicus to Kepler and then Newton. Galileo helped in two ways: first by making new discoveries with the telesope that raised doubts about the old Ptolemaic sysem, without actually proving the Copernican system; and also he raised awareness of the whole question by starting a dispute with the Catholic authorities, and that served to put the whole debate into the public domain in a big way.

Answer 2

They both have to do with the Laws of Physics and the creation of the subject , "Physics."

Answer 3

Gravity Force and Motion apple fell he wanted to know how

Answer 4

because of his excellent achievements and his great laws

Answer 5

no,

Issac fished Gelileo worked for him.
