While the concept of gravity has been observed and pondered throughout history, the person credited with naming and formalizing the theory of gravity is Isaac Newton.
Isaac Newton and the Apple
According to legend, around 1665 or 1666, Newton developed his theory of gravity after watching an apple fall from a tree. This observation led him to question why the apple fell straight down rather than sideways or upwards. This curiosity spurred him to formulate the laws of universal gravitation.

Understanding Gravity
Newton's theory explained that gravity is a force of attraction between any two objects with mass. The strength of this force depends on the masses of the objects and the distance between them. This discovery was revolutionary, providing the first unified mathematical description of the force that governs both the fall of objects on Earth and the motions of celestial bodies.
- Force of Attraction: Gravity pulls objects together.
- Mass and Distance: The larger the mass, the stronger the attraction, and the further the distance, the weaker the attraction.
Legacy
Newton's work on gravity has profoundly impacted our understanding of the universe. His laws remain fundamental in physics and continue to be taught in educational institutions worldwide. This foundational work underpins much of modern physics and astronomy.
