Question

what was the main conclusion made by the following philosophers 1 major idea for each aristotle , galileo , rene descartes , newton's first law of inertia

Answer 1

Aristotle rejected the notion of inertia, asserting instead that a force must be constantly applied to keep something moving.

Galileo developed a concept of relativity: the mechanical workings of the universe are the same in nature for me as they are for you.

Rene Descartes accepts the existence of inertial motion (uniform or non-accelerating motion) as a natural bodily state alongside, and on equal footing with, the notion of bodily rest.
