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 are the forces governing planetary motions?
Only one force - gravity.
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.
Was newtons theory of gravity just a guess?
No, Newton's theory of gravity was not merely a guess; it was based on rigorous observation and mathematical formulation. He formulated the law of universal gravitation by analyzing the motion of celestial bodies and the effects of gravity on Earth. His work was grounded in empirical evidence, particularly his observations of planetary motions and the falling of objects, which he articulated through mathematical equations. This systematic approach laid the foundation for classical mechanics and significantly advanced our understanding of gravitational forces.
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).
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 wrote the book theory of planetary motions?

How did Newton's approach to understanding planetary motions differ from that of his predecessors?
Kepler used observation data by Brahe to find how planets moved. This is "A posteriori" reasoning (finding the theory after the facts were obtained). Newton used his theories of motion and gravitation to explain the orbital motions. This is "A priori" reasoning (having a theory and using it to explain facts). Kepler was a mystic as well as a scientist, and so was Newton. But they attacked the same problem from two different directions. Kepler searched for and found mathematical relationships inside the data. Newton used mathematical relationships he already had to verify the data's accuracy.
Two main planetary motions?
Revolution (about its primary) and Rotation (about its axis)

What did Copernicus believe the planetary motions were do to?
Nicolaus Copernicus believed that the planetary motions were due to the Earth rotating on its axis and revolving around the Sun, which was at the center of the universe. This heliocentric model challenged the prevailing geocentric view, which placed the Earth at the center. Copernicus argued that this arrangement explained the observed retrograde motion of planets and provided a simpler and more coherent understanding of celestial movements. His ideas laid the groundwork for modern astronomy and changed the way humanity perceived its place in the cosmos.
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 do people do hand motions?
People often use hand motions to emphasize their words, clarify their message, or express emotions nonverbally. Hand motions can help add emphasis, engage listeners, and make communication more effective by incorporating visual cues with verbal information. Additionally, hand motions can facilitate better understanding in situations where language barriers exist.
