Source The Beginning To fully understand Galileo's accomplishments in physics, it is important to see the timeline of his life. But it was our buddy Galileo who began the line of thought and the formalization of experimentation, and we might not have known about it had he forgone publishing his main works, which he eventually did in
During this time, he all but disproved the Aristotelian physics and cosmology that had previously dominated the sciences in Europe. The so-called "father of modern science," his work on proving the heliocentric model of the galaxy brought him into conflict with the Catholic church.
Experiments in Motion The law of falling bodies is one of Galileo's key contributions to physics. It states that objects fall at the same speed regardless of weight or shape.
Through his experiments, Galileo countered the pervasive Aristotelian view, which held that heavier objects fall faster than lighter objects. The distance an object travels, he calculated, is proportional to the square of the time it takes the object to reach the ground. 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 laws of motion.
Geometric and Military Compass InGalileo began selling a geometric and military compass of his own design, though the profits were minimal.
Consisting of two rulers attached at right angles with a third, curved ruler between them, Galileo's compass — known as a sector — had multiple functions.
Soldiers in the military used it to measure the elevation of a cannon's barrel, while merchants employed it to calculate currency exchange rates. Sciencing Video Vault An Improved Telescope While he did not invent the telescope, the enhancements Galileo made to original Dutch versions of the instrument enabled him to make new empirical discoveries.
While early telescopes magnified objects by three times, Galileo learned to grind lenses — an advancement that eventually created a telescope with a magnifying factor of 30x.
With his unprecedentedly powerful telescopes, Galileo was the first to observe the uneven, cratered surface of the moon; Jupiter's four largest satellites, dubbed the Galilean moons; dark spots on the surface of the sun, known as sunspots; and the phases of Venus.
The telescope also revealed that the universe contained many more stars not visible to the naked eye. The Case for Heliocentrism In the 16th century, Polish astronomer Nicolaus Copernicus became the first scientist to promote a model of the solar system in which the Earth orbited its sun rather than the other way around.
Galileo's observations discredited the Aristotelian theory of an Earth-centered solar system in favor of the Copernican heliocentric model.
The presence of moons in orbit around Jupiter suggested that the Earth was not the sole center of motion in the cosmos, as Aristotle had proposed. Furthermore, the realization that the surface of the moon is rough disproved the Aristotelian view of a perfect, immutable celestial realm. Galileo's discoveries — including the theory of solar rotation, as suggested by shifts in sunspots — incurred the wrath of the Catholic Church, which espoused the Aristotelian system.
Upon finding him guilty of heresy inthe Roman Inquisition forced Galileo to rescind his support of heliocentrism and sentenced him to house imprisonment — he would eventually die, still under arrest, in Galileo made original contributions to the science of motion through an innovative combination of experiment and mathematics.
More typical of science at the time were the qualitative studies of William Gilbert, on magnetism and electricity. Sep 10, · What Were Galileo's Contributions to Physics? Updated on August 9, Leonard Kelley. Much of Galileo’s work was rooted in logic. In fact, he set up many of the techniques we consider necessary in science, including experimentation and recording of the results.

- Contributions, History & Accomplishments Learn what makes Galileo's life and work such an important part of the development of the modern scientific approach. Galileo Galilei was born in and he passed away in His contributions to astronomy are a great help to the development of Astronomy and all of his works will be cherished and kept as a part of the history.
Italian scientist Galileo Galilei made major contributions to math, physics and astronomy during the Scientific Revolution of the 16th and 17th Century. The so-called "father of modern science," his work on proving the heliocentric model of the galaxy brought him into conflict with the Catholic church.
Galileo Galilei () Widely regarded as one of the greatest scientists, Galileo Galilei was an Italian astronomer, physicist, engineer and mathematician, who helped shape the scientific revolution during the Renaissance.
