Galileo discovered what laws were broken down as follows:
1, the law of motion: Galileo observed the motion of an object and found that the object would keep moving in a straight line at a uniform speed or stand still without external force. This is called Galileo's law of inertia or the first law of motion.
2. Law of Falling Body: Galileo conducted a series of falling body experiments, and found that the acceleration of free falling bodies with different masses and shapes is constant without air resistance, regardless of the mass of the bodies. This is called Galileo's law of falling body or the second law of motion.
3. Law of inclined plane: Galileo studied the law of sliding on inclined plane, and found that the acceleration of sliding object on inclined plane is related to the angle of inclined plane, but it has nothing to do with the mass of the object when the friction force is ignored. This is the so-called Galileo's law of inclined plane.
Galileo studied the principles of velocity and acceleration, gravity and free fall, relativity, inertia and projectile motion, engaged in applied science and technology research, described the essence of pendulum and "still water balance", invented thermometers and various military compasses, and used telescopes for celestial scientific observation. His contributions to observational astronomy include confirming the phase of Venus with a telescope, discovering Jupiter's four largest satellites, observing Saturn's rings and analyzing sunspots.
Galileo's invention
Galileo invented what decomposition is as follows:
Astronomical telescope: Galileo improved the telescope and made it an effective astronomical observation tool. He used a telescope to observe the astronomical phenomena such as the mountains on the surface of the moon, the satellites of planets and the composition of galaxies, which supported Copernicus' Heliocentrism and laid the foundation for the development of modern astronomy.
2. Thermometer: The air thermometer is an instrument invented by Galileo according to the phenomenon that gas expands with heat and contracts with cold. Also known as "Galileo thermometer", it refers to a tool for measuring temperature according to the principle of thermal expansion and cold contraction of substances, and has been improved several times to become a commonly used temperature measuring device today.
3. Proportional gauge: A kind of "proportional gauge" was invented by using the principle that similar triangles's corresponding edges are proportional, which can be used to calculate multiplication, division and proportion.
