Galileo+and+Gravity

=Galileo and Gravity=

Galileo was known mainly for discoveries with his telescope but that’s not the only experiments that he did. Galileo also did a couple of discoveries that have to do with gravity .One of those experiments was his experiment at the leaning tower of Pisa. The thing that he was trying to prove was that objects that fall have the same acceleration towards the earth but the thing that affects them is the air resistance. When he did the experiment he proved that that is true. The way that he proved this is that he dropped to balls with different mass. When he did this the balls fell toward the ground and hit the ground at the same time. This experiment proved Aristotle’s theory that things fall towards the ground relative of their mass false. After that he did the experiment with a hammer and a feather and said that if there would be no air resistance than the hammer and the feather would fall to the ground at the same time because gravity pulls them the same.When Apollo 15 landed on the moon they did this experiment and Galileo was right the feather and the hammer fell to the ground at the same time.

This proves that science is a series of experiment and thru the experiments new theories are established and old theories are proved wrong because Aristotle's theory was proved wrong and Galileo was right.
