What did Kepler notice about the speed of planets as they orbit the sun?
He noted that the speed of the planets changed, moving faster as they approached the Sun, and slowing down as they moved away. His work paved the way for Newton to develop calculus to describe the overall effects of minuscule but continuous changes.
Can the vectors of equal magnitude be combined to give a zero resultant?
By all means. Using Newton's third law (f=ma) Multiply the vectors by 0 and you're home
What did Johannes Kepler do?
He simply discovered many things that makes technology where we are! -m In astronomy he used measurements made by Tycho Brahe to do many complicated calculations to discover the shape of the planets' orbits. The results were published as the three laws of planetary motion in 1618. They were found to give good results when used to predict the future positions of the planets. For this work Kepler is recognised as one of the founders of modern astronomy. ________________________________ Kepler worked with Tycho Brahe for several years. Brahe had no great skill in science or mathematics, but was a METICULOUS and precise observer. Based largely on Brahe's observations, Kepler was able to determine that the planet Mars - and by extension, all the other planets - traveled in elliptical paths under the influence of a force that was inversely proportional to the square of the distance between the Sun and the planet. This paved the way for Newton's development of calculus and the math that describes gravity.
What is the difference between a Newton and a newton?
Newton- Sir Isaac Newton newton- a unit of measure units of measure are not capitalised, though their abbreviations may be: one newton = 1 N, one pascal = 1 Pa
How much geometry did Newton use to create calculus?
Calculus is essentially the collection of geometry, algebra, smarts, and arithmetic - all combined to help solve a greater problem that geometry, algebra, smarts, or arithmetic cannot solve on its own.So basically, Newton used all of geometry to help developcalculus.Calculus was already developed centuries ago in ancient China, India, and Egypt.
What evidence do you have that the planets move in elliptical orbits around the sun and not in circular orbits?
Elliptical orbits of the planets around the sun actually match what we observe. Newton's Theory of Universal Gravitation states that planets will move around the sun in elliptical orbits.
Why do planets have circular and elliptical motions in the solar system?
The scientific explanation lies in Kepler's laws of planetary motions, which were discovered by Newton to be linked with the law of gravity. All the planets have elliptical orbits, and many of those are close being circular.
Why planets are revolving in elliptical orbits?
Kepler's first law of planetary motion published in 1618 says that the planets travel in elliptical orbits with the Sun at one focus. Newton's law of gravity and other work he did explains how the Sun's gravity produces ellpitical orbits.
Who discovered the elliptical path of the planets?
Johannes Kepler discovered that the planets follow elliptical paths around the Sun. This was a significant advancement in understanding the motion of celestial bodies and laid the foundation for his laws of planetary motion.
Newton learned that the orbits of planets are the result of what two forces?
Newton learned that the orbits of planets are the result of the gravitational force between the planet and the Sun, which causes the planet to move in an elliptical orbit, and the planet's inertia, which causes it to continue moving in a straight line.
How did Newtons work on orbits add to the work Kepler had done?
Newton's work on orbits built upon Kepler's laws by providing a theoretical explanation for why planets follow elliptical paths around the Sun. Newton's laws of motion and law of universal gravitation helped to show that these elliptical orbits were a consequence of a gravitational force between the planets and the Sun, providing a deeper understanding of the underlying mechanics of planetary motion.
How did newton's theories explain why planets orbit the sun and why moons orbit?
Kepler found from observations that the planets move in elliptical orbits. Newton then showed with his theoretical discoveries that the force of gravity from a massive central object produces elliptical orbits in smaller objects. The theories he used were the law of gravity, the laws of motion and the differential calculus. Using these he showed that an object in an elliptical orbit is continuously accelerating towards the central object. Its sideways velocity and mass prevent it from falling directly in.
Newton was the first to understand that gravitation caused planets to follow irregular orbits?
It was actually Johannes Kepler who discovered that planets follow elliptical orbits in the early 17th century. Newton later built upon Kepler's work by formulating the law of universal gravitation, explaining the underlying force responsible for the motion of planets.
What were the two factors Isaac Newton concluded that combined to keep the planets in orbit?
Isaac Newton concluded that the force of gravity and the forward motion of the planets combined to keep them in orbit around the Sun. The force of gravity pulls the planets towards the Sun, while the forward motion of the planets creates the centrifugal force that counteracts gravity, leading to stable orbits.
What evidence do you have that planets move around the sun in an elliptical orbit?
That theory is supported by observation, and is predicted by other theory that isconfirmed by both observation and experiment.1). A system of planets moving around the sun in elliptical orbits is the simplest structurethat produces the motions of the planets that we actually see in the sky.(demonstrated by Kepler, working with Tycho's observational data)2). A theory of universal gravitation, proportional to the product of masses and inverselyto the square of the distance between masses, predictsthat planets will move aroundthe sun in elliptical orbits.(Newton)
Did Newton discover that gravitation caused planets to follow irregular orbits?
No, Isaac Newton discovered that gravitation causes planets to follow elliptical orbits. This was a major breakthrough in understanding celestial motion and laid the foundation for his law of universal gravitation.
How is Newton's law of gravity related to the movement of the planets?
How is Newton's law of gravity related to the movement of the planets?
