Fundamental ideas of modern celestial mechanics were established by:
Correct answer: B. Newton
- A. Kepler & Galileo
- B. Newton
- C. Robert Hook
- D. Tycho & Halley
Explanation
Sir Isaac Newton's work, especially outlined in his monumental work "Philosophiæ Naturalis Principia Mathematica" (Mathematical Principles of Natural Philosophy), published in 1687, established the fundamental principles of celestial mechanics. Newton formulated the laws of motion and the law of universal gravitation, which explained not only how objects move on Earth but also how celestial bodies interact with each other. His laws provided a unified and comprehensive theory that explained the motion of planets, moons, and other celestial bodies in our solar system.

About Measurements
Physical quantities are expressed with SI base and derived units, while measurement limits are described through accuracy, precision, absolute and percentage error, and significant figures. Dimensional analysis checks equations, derives relationships and detects inconsistent units, but it cannot determine numerical constants or distinguish quantities with identical dimensions.
