According to the story, Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle's theory of gravity (which states that objects fall at speed proportional to their mass)
Khadijamurad:
but it is directly from google
thank you
but how can thr acceleration be same when the masses are different and also the air resistance must be acting there so according to me the conclusion of his experiment is not clear to me
pls explain it in comments itself
kindly hurry up
According to the traditional account, to refute the Aristotelian notion that heavier objects fall faster than light ones, Galileo performed an experiment from the top of the leaning tower of Pisa. He dropped two spheres of different weight and observed that both hit the ground at the same time.

Explanation:
- Galileo took the marble, a ramp and started the experiment by rolling it down the ramp.
- Using a water clock, Galileo measured the time it took for the rolling ball to reach a known distance down the inclined plane.
- After numerous trials, it was noted that the time taken for the ball to roll the entire length of the ramp was equal to double the amount of time it took for the same ball to only roll a quarter of the distance.
- In short, if one doubled the amount of distance the ball travelled, it would travel four times as far. Through this experiment, Galileo concluded that, if an object is released from rest and gains speed at a steady rate (as it would in free-fall or when rolling down an inclined plane), then the total distance, s, travelled by the object is proportional to the time squared needed for that travel.
- Mathematically s ∝ t2
- This was the basis for Newton’s first law of motion.
