Galileo and The Leaning Tower of Pisa experiment

Aristotle (384-322 SM), ilmuwan dan filsuf Yunani, meyakini bahwa benda-benda yang berat jatuh lebih cepat daripada benda-benda yang lebih ringan, dan prinsip ini diterima sebagai suatu kebenaran selama beratus-ratus tahun. Hingga kemudian pada abad ke enam belas, Galileo melakukan suatu percobaan dengan menjatuhkan dua buah  logam dari menara miring Pisa. Terlepas dari fakta bahwa berat salah satu logam adalah dua kali berat logam yang lain, keduanya menyentuh tanah pada waktu yang sama.

Aristotle (384–322 B.C.), Greek scientist and philosopher, believed that heavy objects fall faster than lighter ones, and this principle was accepted as true for hundreds of years. Then in the sixteenth century, Galileo produced a counterexample by dropping two pieces of metal from the Leaning Tower of Pisa. In spite of the fact that one was twice as heavy as the other, both hit the ground at the same time.

For the demonstration and more explanation, we can see on this following link:
