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 was not part of Kepler's laws of planetary motion?
Kepler's laws of planetary motion do not address the gravitational forces that govern planetary movements, nor do they explain the nature of the forces acting on the planets. Additionally, they do not account for the elliptical orbits being influenced by other celestial bodies, such as the gravitational pull from nearby planets or stars. Instead, Kepler focused on the geometric relationships and patterns of planetary orbits around the sun.
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 foud out why the moon stays up in the sky?
Isaac Newton is credited with discovering why the moon stays in the sky through his work on gravity. He formulated the law of universal gravitation, which explains that the moon is held in orbit around the Earth due to the gravitational pull between the two bodies. His insights laid the foundation for our understanding of celestial mechanics and the forces governing planetary motion.
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.
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.
