He wrote the first work which refers to that line of study as "Physics" – in the 4th century BCE, Aristotle founded the system known as Aristotelian physics. He attempted to explain ideas such as motion (and gravity) with the theory of four elements.

Physics is a challenging subject ─ it's a combination of math and science that can be difficult even for the best of us. But despite its challenging nature, with a few basic tips and a little practice there's no reason you can't succeed.

Galileo Galilei, an Italian mathematician, astronomer, and physicist, earned the title 'Father of Physics' due to his major contribution to finding the motion of bodies and the development of the telescope.
