The Greek philosopher Aristotle dominated scientific thought for many years. The first major blow to the ideas of Aristotle came in the sixteenth century when Nicolaus Copernicus published his model of the universe centered on the sun. Galileo Galilei was the next to challenge the ideas of the Greek philosopher. But it was René Descartes, who would add new depth and dimension to the inertial movement. In his "Principles of philosophy", Descartes proposed three laws of nature.

For Newton to establish the three laws of motion he had to go through various processes of different philosophers. And each of these philosophers giving different points of view, discovering these laws and Newton was the one who concluded them.

Newton had to study each of these philosophers in order to conclude all these laws since by the time the last philosopher modified these laws, Newton was a newborn.

Yes, they are useful because they are the easiest and simplest way to explain the movement and describe various aspects with simple formulas.
