Who discovered gravity?

• A. Albert Einstein
• B. Isaac Newton
• C. Galileo Galilei
• D. Nicolaus Copernicus

Answer: (B)

The correct choice is Isaac Newton, who is credited with the formulation of the law of universal gravitation. In the late 17th century, Newton proposed that every mass attracts every other mass in the universe through a force that we now call gravity. His key insights showed how the gravitational force explained not only the falling of an apple but also the motion of planets and the moon, fundamentally changing our understanding of physics and astronomy. Newton's work was encapsulated in his famous work, "Mathematical Principles of Natural Philosophy" (often referred to as the Principia), where he outlined his laws of motion and the law of universal gravitation. This laid the groundwork for classical mechanics and provided a clear mathematical framework for understanding gravitational forces, which had lasting implications for both science and engineering. While Albert Einstein later developed the theory of general relativity and offered a more nuanced understanding of gravity, it was Newton's earlier work that established the foundational concepts of gravitational theory. Galileo Galilei contributed to the study of gravitation through his experiments and observations, notably regarding the acceleration of falling bodies, but he did not formulate a comprehensive theory of gravity as Newton did. Nicolaus Copernicus is known for his heliocentric model of the solar system, shifting
