Galileo Galilei is viewed as the father of physics because of his significant scientific contributions and his influence on other major scientists, such as Johannes Kepler and Isaac Newton. During his time, from 1564 to 1642, people relied on past teachings to study mechanics. However, Galileo strongly believed in experimentation and made experiments the basis of his scientific investigations. In addition, Galileo advocated for physics to be a science founded on mathematics. Equipped with his new methods of study, he noticed that many theories in physics were incorrect and focused on improving them.

Galileo was famous for his laws of motion, which held that when there is gravity, all bodies accelerate at the same rate regardless of size and mass. Galileo’s findings in the laws of motion went against Aristotle’s theories. They included concepts focusing on inertia, velocity, and force. Some of Galileo’s scientific discoveries influenced Isaac Newton’s laws of motion.

In addition, Galileo presented original theories in hydrostatics, astronomy, and optics. One of Galileo’s inventions is the hydrostatic balance. Through his experiments, Galileo also made important discoveries regarding the movements of pendulums. In particular, Galileo discovered that pendulums have a constant period—that is, the time a pendulum takes to finish one oscillation.
