Jan 9, 2026 · The manuscript tract De motu (On Motion), finished during this period, shows that Galileo was abandoning Aristotelian notions about motion and was instead taking an Archimedean approach …

Oct 7, 2025 · Galileo’s insight was subtle but monumental: motion is not sustained by force but altered by it. This overturned the ancient Aristotelian worldview and opened the door to classical mechanics.

Galileo's study of the motion of pendulums and other oscillating systems laid the groundwork for the understanding of periodic motion and the concept of frequency, which is crucial in the study of …

Galileo’s greatest contributions to science lay in his work on understanding motion. Galileo was able to show that the increase in velocity of a falling object was proportional to the time it was falling (hence …

This was incorporated into Newton's laws of motion (first law), except for the direction of the motion: Newton's is straight, Galileo's is circular (for example, the planets' motion around the Sun, which …

Using geometric analysis, Galileo demonstrated that the horizontal and vertical components of a projectile’s motion could be treated independently, a key insight in understanding complex systems …

Apr 23, 2018 · Galileo also first developed the concept of inertia — the idea that an object remains in rest or in motion until acted on by another force — which became the basis for one of Isaac Newton's …

We know very little indeed of Galileo during his first ten years at Padua: throughout this time-and the years between the ages of 28 and 38 may well be significant in a man's life-there is no evidence …

Aristotle knew only a state of rest and a state of forced motion, a moveable object moved by a mover. Galileo insisted on this. Galileo insisted on unperturbed motion horizontally at constant speed, …

Jul 15, 2023 · Galileo studied the motion of pendulums and made important discoveries about their behavior. He found that regardless of the amplitude of the swing, the time it takes for a pendulum to …
