He used inclined planes to slow down the effects of gravity. He also dropped two things of different weights to prove that they reached the ground at the same time (which it is suposed to do, but does not always because of air drag).

Law of conservation of momentum was first discovered by Gallileo, when he proved that two objects of different masses thrown from a tower reach the destination at the same time.

before galileo, people thought that heavier objects fell faster than lighter objects. however, galileo didn't believe them. instead, he dropped 2 objects from the leaning tower of pisa- one was a heavy ball, and the other was a light ball. both hit the ground at the same time, which proved that the earth's gravity makes all objects accelerate downward at the same rate (specifically, 9.8 m/s/s). this theory doesn't take drag into account.

I'm not sure of the year, but I believe that he went up to the leaning tower of Pisa and dispensed both a cannonball and a feather and timed the descent to the ground.

I think he dropped 2 objects of large weight difference and both fell at the same rate.
