C: Galileo Galilei

Galileo Galilei was a renowned scientist who lived in Italy during the height of the Catholic Counter-Reformation when the Catholic Church fought hard to retain its power. Galileo was a brilliant man who worked on concepts of motion. In one experiment, Galileo disproved a classic Aristotle idea that a pendulum swings at a slower rhythm as it approaches its resting place, instead, found out that each swing of the pendulum took exactly the same amount of time. Another one of Galileo’s experiments on motion involved the acceleration of a falling object. The traditional legend of this famous experiment places Galileo at the famous Leaning Tower of Pisa. Galileo wants to show that objects of different weights will fall at the same rate. In order to prove this idea, Galileo stood at the top of the Leaning Tower of Pisa with two cannonballs of different rates and performed the following experiment:
