What were Kepler's modifications to Copernicus's model of planetary motion?
Understand the Problem
The question is asking about the contributions of Johannes Kepler to the understanding of planetary motion, specifically regarding his modifications to Copernicus's model. It requires filling in specific terms related to Kepler's findings.
Answer
Kepler described orbits, used Brahe's data, established laws, and noted elliptical orbits and faster motion near the Sun.
Johannes Kepler accurately described the orbits of the planets. Used data collected by Tycho Brahe. Constructed the laws of planetary motion. Demonstrated that orbits were elliptical. Determined that planets move faster when closer to the Sun.

Johannes Kepler accurately described the orbits of the planets. Used data collected by Tycho Brahe. Constructed the laws of planetary motion. Demonstrated that orbits were elliptical. Determined that planets move faster when closer to the Sun.
More Information
Kepler's laws transformed our understanding of the solar system by providing an accurate model of planetary motion. His work paved the way for Newton's laws of motion and universal gravitation.
Tips
A common mistake is confusing the shape of planetary orbits. Kepler was the first to confirm they are elliptical, not circular.
