Galileo's falling bodies experiment. Caricature artwork depicting the experiment on falling bodies said to have been carried out by the Italian physicist Galileo Galilei (1564-1642). This experiment involved dropping two bodies of different weights from the Leaning Tower of Pisa. According to Aristotle, heavy bodies fell faster than lighter ones. Galileo corrected this with his discovery that objects fall with the same acceleration regardless of their weight. Galileo was said to have used two cannonballs. A famous recreation of the experiment on the Moon in 1971 used a hammer and feather. For a caricature of this, see images C011/3599 and C011/3600.
