The Galileo's Thought Experiment

Galileo's thought experiment considers two objects of different masses dropped from the same height. He hypothesized that if gravity pulls equally on all objects, then regardless of mass, both should land simultaneously. Traditionally, it was believed heavier objects fall faster. Galileo challenged this, reasoning that if air resistance is accounted for and ignored, all objects should hit the ground together. This experiment fundamentally demonstrated that the acceleration due to gravity is constant for all objects, regardless of their mass, which was a crucial step in understanding the laws of motion and universal gravitation.
