Answer:
Heavier objects fall faster than lighter ones
Step-by-step explanation:
Galileo's leaning tower of Pisa experiment is famously known, where in he dropped two objects having different mass and both reached ground at the same time. He demonstrated that it does not depend on the mass of the object. All the object fall under equal acceleration due to gravity and thus, reach at the same time. Galileo corrected Aristotle's explanation of motion that heavier objects fall faster than lighter ones.
