What evidence did Galileo?
Galileo’s main pieces of evidence were the phases of Venus, the eclipses of Jupiter’s moons, the existence of tides (which Galileo believed could only occur if the Earth moved), observable planetary speeds, and the distances of planets from the Sun.
How did Galileo prove his theory?
It was Galileo’s observations of Venus that proved the theory. Using his telescope, Galileo found that Venus went through phases, just like our Moon. Galileo concluded that Venus must travel around the Sun, passing at times behind and beyond it, rather than revolving directly around the Earth.
What is some of the evidence used by Galileo to support Copernicus model and disprove?
Galileo discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter. Beginning on January 7, 1610, he mapped nightly the position of the 4 “Medicean stars” (later renamed the Galilean moons).
What did Galileo’s telescope reveal?
With this telescope, he was able to look at the moon, discover the four satellites of Jupiter, observe a supernova, verify the phases of Venus, and discover sunspots. His discoveries proved the Copernican system which states that the earth and other planets revolve around the sun.
What did Galileo prove about falling objects?
Galileo Galilei—an Italian mathematician, scientist, and philosopher born in 1564—recognized that in a vacuum, all falling objects would accelerate at the same rate regardless of their size, shape, or mass. He arrived at that conclusion after extensive thought experiments and real-world investigations.
What did Galileo’s experiment prove?
According to the story, Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle’s theory of gravity (which states that objects fall at speed proportional to their mass).
How did Galileo’s observations support Copernicus model of the universe?
How did Galileo’s observations of Jupiter support Copernicus’s model? There are four moons orbiting Jupiter, they wouldn’t be orbiting Jupiter if Earth was at the center of the system. Venus is near the sun, and it goes through phases; it wouldn’t go through phases if Earth was at the center if the system.
What is some of the evidence used by Galileo to support Copernicus model and disapprove Aristotle and Ptolemy’s?
Galileo found Venus went through the entire phase cycle, proving that she revolved completely around the Sun, as predicted by Copernicus in his heliocentric model. (Galileo, through his telescope, perceived that Venus exhibited phases life that of our moon.
What is Galileo’s proportional compass?
The sector, also known as a proportional compass or military compass, was a major calculating instrument in use from the end of the sixteenth century until the nineteenth century. It is an instrument consisting of two rulers of equal length joined by a hinge.
What were Galileo’s achievements?
10 Major Accomplishments of Galileo Galilei
- #1 He invented a hydrostatic balance.
- #2 Galileo invented a forerunner to the modern thermometer.
- #3 He is credited with the invention of an improved military compass.
- #4 Galileo discovered that pendulums were isochronous.
What was the result of Galileo’s experiment?
One result of the experiment surprised Galileo, and one surprises us. Galileo found that the heavy ball hit the ground first, but only by a little bit. Except for a small difference caused by air resistance, both balls reached nearly the same speed. And that surprised him.
What is Galileo’s theory of motion?
Galileo’s laws of Motion: determined that the natural state of an object is rest or uniform motion, i.e. objects always have a velocity, sometimes that velocity has a magnitude of zero = rest. objects resist change in motion, which is called inertia.
