The discovery of gravity is attributed to Sir Isaac Newton.
Sir Isaac Newton and the Law of Universal Gravitation
Sir Isaac Newton is renowned for his monumental contributions across various fields, including physics, mathematics, and optics. However, his most famous achievement is the formulation of the Law of Universal Gravitation. This groundbreaking theory revolutionized our understanding of how celestial bodies interact and why objects fall to the ground.
Newton's Key Contributions
- Formulated the Law of Universal Gravitation: This law states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
- Unified celestial and terrestrial mechanics: Newton demonstrated that the same force of gravity that makes an apple fall from a tree also governs the motion of the moon around the Earth and the planets around the sun.
- Development of Calculus: While developing the mathematics necessary for his work on gravity and physics, Newton also co-created calculus, an incredibly powerful mathematical tool.
The Story of the Apple
The popular story of the apple falling from a tree and inspiring Newton's idea about gravity might be a simplified version of how he began thinking about the topic. However, it highlights how everyday experiences could lead to profound scientific discoveries.

Newton's work on gravity not only revolutionized physics but also shaped how we understand the universe. His insights continue to be foundational in fields like astrophysics and cosmology. He was born especially tiny but grew into a massive intellect and still looms large, thanks to his findings on gravity, light, motion, mathematics, and more.
