Kepler's Laws of Planetary Motion:
1] Each planet moves in an elliptical orbit with the sun at one focus
2] The line form the sun to any planet sweeps out equal areas of space in equal time intervals
3] The squares of the times of revolution (days, months or years) of the planets are proportional to the cubes of their average distances from the sun.

∙ 9y agoAll planets move around sun in elliptical orbits having sun at one focus of orbit. The areal speed of a planet around the sun is constant. The square of the period of revolution(T) of any planet around the sun id directly proportional to the cube of its mean distance (a) from the sun.

Who was the scientist who showed that gravity accounts for keplers laws of planetary motion?
Isaac Newton
What was Johannes Kepler known for?
Johannes Kepler(1571-1630) was a German astronomy and natrual philosophere who was known for his ability in formulating and verifying the three laws of planetary motion, which are now known as Keplers's Laws.
Keplers law that describes how fast planets travel at different points in their orbits is called the law of?
This is known as Keplers 2nd Law of Planetary Motion. It states that line drawn between a planet and the sun sweeps out equal areas during equal time intervals.
What year did Kepler accomplish the Keplers laws?
Kepler's Laws of Planetary Motion:1] Each planet moves in an elliptical orbit with the sun at one focus2] The line form the sun to any planet sweeps out equal areas of space in equal time intervals3] The squares of the times of revolution (days, months or years) of the planets are proportional to the cubes of their average distances from the sun.
How is the mass of the planet related to the amount of gravity?
Gravity is what keeps the planets orbiting round the Sun instead of disappearing off into outer space. We feel a constant gravity force - our weight - holding us down on the Earth's surface. Isaac Newton was the first one to postulate a gravity force that depends on distance. His idea was a force acting on each planet that varied with the inverse square of the planet's distance from the Sun. He was able to prove that if this was the law of gravity in the solar system, then the planets' orbits must follow Keplers' three laws. Kepler formulated his laws from Tycho Brahe's observations of the planets' positions, but it was many years later that Newton came up with the theory that confirmed these laws. People then realised that Keplers' laws and Newton's laws of motion and the law of gravity were all part of one big theory that all stacked up, and that is what we still believe today.
What does Keplers laws apply to?
Celestial objects in orbit.
What are the rules summarising planetary movements called?
Keplers Laws
Which of Keplers laws is also known as the Harmonic Law?
It is the third law
What was Johannes Keplers major contribution?
Known for his eponymous laws of planetary motion.
What is a word that is related to keplers three laws and starts with the letter m?
Mindboggling? They are "Laws of Planetary Motion". So I guess the answer is "motion".
Who was the scientist who showed that gravity accounts for keplers laws of planetary motion?
Isaac Newton
How did newton explain Kepler's laws?
he supported his ways and thiught of better ways to replace keplers half right ways
Which of Keplers laws says how fast planets travel at different points in their orbit?
Kepler's second law the law of equal areas.
What two things is gravitational field strength dependent on?
Distance from the body and the mass of the body. See Keplers laws of planetary motion for more info.
What was Johannes Kepler known for?
Johannes Kepler(1571-1630) was a German astronomy and natrual philosophere who was known for his ability in formulating and verifying the three laws of planetary motion, which are now known as Keplers's Laws.
What was the date of Keplers theory?
April 27, 4977 B.C. That was when he once calculated that the universe began. Or, you may mean when he published his Laws of Planetary Motion. He published his first 2 laws in 1609 and his 3rd law around 1619.
Which of keplers laws states the planets move in an ellipse?
It is Kepler's first law which says the planet moves in an ellipse with the Sun occupying one focus and the other focus is vacant.
