How did newton's approach to understanding planetary motions differ from his predecessors?
Newton's approach to understanding planetary motions fundamentally differed from his predecessors by introducing a mathematical framework grounded in universal laws. While earlier thinkers like Kepler relied on empirical observations and geometric models, Newton formulated the law of universal gravitation, explaining that gravitational forces govern the motions of celestial bodies. This shift from qualitative to quantitative analysis allowed for a cohesive explanation of both terrestrial and celestial mechanics, unifying them under a single set of principles. Newton's emphasis on mathematics established a new standard for scientific inquiry that profoundly impacted the study of physics and astronomy.
What is the difference between newton and Kepler theories?
Newton's theories, primarily articulated in his laws of motion and universal gravitation, describe how objects interact through forces, emphasizing the mathematical relationships between mass, distance, and gravity. In contrast, Kepler's theories focus on the motion of planets, specifically their elliptical orbits around the sun, outlined in his three laws of planetary motion. While Kepler's work provided the observational framework for planetary motion, Newton's laws offered the underlying physical principles that explain why those motions occur. Essentially, Kepler described the "how" of planetary motion, while Newton explained the "why."
Who was T A Carrington?
T. A. Carrington was a British astronomer and mathematician known for his work in planetary astronomy. He made significant contributions to the understanding of the orbits and motions of the planets. Carrington is best known for his calculation of the rotation period of the sun.
Who analyzed the motions of planets?
Tycho Bache and Johannes Kepler. Tycho watched and records tons of data of the moments of planets, but his assistant, Johannes Kepler analyzed it all and made theories about the movements to better understand them (this was after Tycho passes away).
How does gravity affect planetary motion?
The mutual gravitational forces that attract a planet and the sun to each other are responsible for keeping the planet in orbit around the sun.
What are forces governing planetary motion?
Only one force - gravity.
What did Copernicus believe the planetary motions were due to?
3r
Who wrote the book theory of planetary motions?
Johan kepler.
Two main planetary motions?
Revolution (about its primary) and Rotation (about its axis)
How are plates motions connected with motions within the rest of the earths mantle?
convection currents in the mantle provide the basic driving forces for plate motions.
How are plate motions connected with motions within the rest of earth's mantle?
convection currents in the mantle provide the basic driving forces for plate motions.
What is the study of motion and forces?
Kinematics is the study of motions Kinetics is the study of forces
One of the major forces that influence planetary motion?
Gravity.
What did Isaac Newton use to describe forces and motions?
He used mathematics.
Do force always got to cause motions?
No. A non-moving object has forces acting on it, but the forces are in balance in such a case.

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.
