Why did Galileo perform experiments to see if all objects fall with the same acceleration?

Galileo performed experiments to investigate whether all objects fall at the same acceleration regardless of their mass, challenging the prevailing Aristotelian belief that heavier objects fall faster than lighter ones. By conducting experiments, such as rolling balls down inclined planes and dropping various weights from the Leaning Tower of Pisa, he aimed to demonstrate that the acceleration due to gravity is constant for all objects in free fall. This groundbreaking work laid the foundation for modern physics and the understanding of gravitational acceleration.
