Everyone after Isaac newton, who could understand both gravity and orbits,
and had enough geometry and calculus to be able to apply one to the other.
What else can I help you with?
How did newtons work on orbits add to work Kepler had done?
Newton derived Keplars findings from Newton's Theory of Gravity. Thus, newton 'explained' the basis for Keplars findings and extended them.
What alternative will be used- newton discovered or invented the theory of gravitation?
It is more correct to say that Newton invented the theory of gravitation, than to say that he discovered the theory. Gravity exists in nature, but the theory of gravity does not exist in nature, it is a human invention. You can only discover something that already exists, and the theory of gravity didn't exist until Newton invented it.
What planets did newton used to discover his theory of gravity to show its effects on Uranus?
Neptune.
How did astronomy resolve the issue of the geocentric theory versus the heliocentric theory during the scientific revolution?
First there were several different theories put forward to explain the movements of the planets. The main ones are Ptolemy (geocentric) and then Copernicus (heliocentric). Both theories explained the positions of the planets within the accuracy of the observations that were made at the time (up to the 1580s). Both theories used combinations of circles to model the planets' orbits. Then Tycho Brahe came on the scene with much improved equipment for measuring the planets' positions with unprecedented accuracy. Although Tycho believed in the geocentric idea, his observations were used by Johannes Kepler to create a new heliocentric theory in which the planets move in elliptical orbits, published in 1609. At that time there was no way of knowing which theory was right, except that Kepler's theory fitted the observations best. By the end of the 1600s, scientists had made significant discoveries in dynamics, the science of moving objects, and in gravity. The laws of motion and the law of gravity were used by Isaac Newton to prove theoretically that a planet in the Sun's gravity field must move in an elliptical orbit. This achievement put Kepler's theory in the spotlight, where it has been ever since. Apart from tiny corrections from relativity, Kepler's heliocentric theory is the one still used today.
What is the formula used to calculate the weight of an object if you were given the mass in kilograms?
weight=mass*gravity
Kepler used Brahe's observations to show that the orbits of the planets are?
Johannes Kepler said that IF the planetary orbits are elliptical,THEN that would explain the measurements that Tycho Brahespent his whole life collecting.Isaac Newton said that IF gravity works the way he thought it does,THEN the planetary orbits have to be elliptical.But neither Kepler nor Newton could ever say that the orbits are REALLY ellipses.Both of their statements are 'only theories', just like the theory of evolution.They have never been proven.
How were Copernicus' and Kepler's theories about the movement of the planets similar How were they different?
Copernicus started the ball rolling with a new theory explaining how the planets move, using circles and epicycles as Ptolemy had done, but with the Sun assumed to be at the centre. He claimed that the new theory was simpler than Ptolemy's theory, which was later found to be not actually the case. But Copernicus's theory was used to predict the positions of the planets. Later Tycho Brahe found ways of making accurate measurements of the planets' positions, and discovered small errors in predictions that were based on Copernicus's theory. Kepler retained the idea that the Sun is at the centre, but used Tycho's measurements to research a new detailed theory of the planets' orbits. After long and arduous studies he discovered that the orbits are elliptical, and published three laws of planetary motion which were a huge step forward in scientific knowledge. Newton made further discoveries that explained how elliptical orbits are produced by the Sun's gravity. He said he had stood on the shoulders of giants, and Kepler must have been at the front of his mind. Kepler's achievement is enormous because the difference between an ellipse of the type that the planets move in and a circle with the Sun offset from the centre - as predicted by the old theory with epicycles - is extremely small.
How did Galileo help prove that Copernicus' theory about the solar system was right?
He didn't know it, he just brought out a new theory that showed that with the Sun at the centre the planets' paths could be explained more simply. That was in 1543 and Kepler produced another heliocentric theory in 1609 which had the planets moving in elliptical orbits round the Sun. The only thing in favour of Kepler's theory at the time was that it explained the planets' positions more accurately than previous theories. But 80-90 years later Newton's discoveries in gravity and the laws of motion were used to prove by theory that the planets must move in elliptical orbits.
Contribution of tycho brahe to science?
He took many measurements regarding the Orbits of planets which Keplar then used to formulate his 3 laws. This eventually was part of the prompting for Newtons law of gravity.
What were Nicolaus Copernicus Galileo Galilei Tycho Brahe Johannes Kepler?
Copernicus 1473-1543 was a Polish priest who reworked the Ptolemaic model of the planets which had the Earth at the centre (geocentric) by instead placing the Sun at the centre (heliocentric).Both models used circles and epicycles to represent the planets' orbits, which was a reasonably good model for elliptical orbits of low eccentricity.Predictions from these theories were accepted until the quality of measurements of actual positions eventually showed problems.Tycho 1546-1601 was a Danish nobleman who set up the best and most accurate measuring systems ever known for observing the positions of stars and planets, with higher accuracy than ever before achieved.Galileo 1564-1642 adopted the Copernican theory and had a famous battle with the catholic church authorities over whether the heliocentric theory was the absolute truth rather than the geocentric theory as taught by the church at that time.He was eventually forced to accept the church's teaching for lack of evidence to support the heliocentric theory, but long after his death the heliocentric theory became accepted everywhere.Kepler 1571-1630 was a mathematical assistant to Tycho, an employee, who used the new measurements to calculate that the planets' orbits are elliptical and that the orbits obey three laws known as Kepler's Laws.These were later combined mathematically with Newton's law of gravity and the laws of motion, using differential calculus, to show why Kepler's laws were correct. They were also used to find the planet's masses and the Sun's mass.
Who was originally proposed heliocentric theory?
Nicholas Copernicus developed the heliocentric theory .It use to be the Copernicus Theory.Later when Galieo invented the teloscope he proved it true And renamed Heliocentric TheoryNicoluas Copernicus was the first astronomer to propose the heliocentric theory.The heliocentric theory was first proposed by the Greek astronomer and mathematician Aristarchus of Samos, in the 3rd century, BCE.The first predictive heliocentric mathematical model of the motion of the planets was developed by Nicholas Copernicus.
How does comet Halley's orbital speed change as it orbits the sun?
It accelerates towards the star. This is due to the increased force of gravity which is inversely proportional to the square of distance between the masses; as they get closer, gravity pulls harder. An increased force means a greater acceleration due to gravity.
