Who is thomas Kepler and what did he have to do with physics?

Answer 1

How did Johannes Kepler impact astronomy in modern day life?

Are Johannes Kepler's laws still in effect today?

No. By the early 19th Century, Kepler's Laws were deemed to be outmoded,

and had frankly become somewhat moldy. By popular demand, especially from

the younger folks, the Laws were repealed in 1842, and they no longer hold

any force today.

Answer 2

Kepler was the first astronomer to accurately describe the motion of planets. His three laws of planetary motion are as follows.

The orbit of every planet is an ellipse with the Sun at one of the two foci.

A line joining a planet and the Sun sweeps out equal areas during equal intervals of time.

The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.

Answer 3

Our model of how the Solar System operates was discovered by Kepler with his three laws of planetary motion, published in 1609.

He took an entirely new approach to planets' orbits after new and accurate observations of the planets' positions had been carried out by Tycho Brahe with the latest equipment. After a lot of detailed geometric work on the orbit of Mars Kepler found that an elliptical orbit fitted the way Mars moves, more closely than anything else.

From that he deduced the famous three laws. However it was not until the time of Isaac newton that they started to understand why the planets move as they do, after the force of gravity was discovered. Newton's major discovery was that when the planets move under the inverse-square law of gravity, they must follow Kepler's three laws.

The circles and epicycles of Copernicus's system represent the planets' orbits with good accuracy provided the eccentricity factor is small. This theory was replaced by that of Kepler. Kepler's decision to study Mars, which has an orbit with 9% eccentricity (higher than the other major planets) was a good choice because it shows up the difference. Even with this eccentricity the the minor axis of the orbit is less than 0.5% shorter than the major axis.

Answer 4

Keplar figured out the earth orbit using Tycho Brahe's data. This verified Copernicus' Heliocentric Theory. Keplar gave the laws of period and radius, later verified by Newton's Gravitational Theory.

Answer 5

I'm not aware of a person named "Thomas Kepler." Perhaps you meant Johannes Kepler, a 17th-century astronomer and mathematician known for his laws of planetary motion. Kepler's work laid the foundation for Newton's laws of motion and his research significantly contributed to the advancement of physics, particularly in the field of celestial mechanics.

Answer 6

Pre newton, laid down basic orbital mechanics

Answer 7

He was the first to recognize that planets move in elliptical orbits.

Answer 8

he made the theory of motion

Answer 9

The theory of planetary motion..
