The Physics of Aristotle vs. the Physics of Galileo. Aristotle taught that the substances making up the Earth were different from the substance making up the heavens. He also taught that dynamics (the branch of physics that deals with motion) was primarily determined by the nature of the substance that was moving.

Furthermore, what is the difference between Aristotle and Galileo?

The way Aristotle believed objects fall on the Earth Aristotle's theory of motion was different than Galileo's. He also believed that objects fell faster than others because of their size and mass. Therefore, if two balls were dropped from the same height, the bigger and heavier one would hit the ground first.

Additionally, how did Aristotle influence Galileo? Aristotle, a Greek philosopher, came up with a theory that greatly influenced Galileo. Aristotle believed that things beyond the earth were perfect, such as the moon, with it's smooth surface. However, Galileo believed differently. Using his telescope, he studied the moon, and quickly saw an uneven surface.

Then, how did Galileo contradict Aristotle?

Aristotle did not believe in the void and thought the universe was a continuum. Galileo refined the concept of inertia. Galileo did not believe the ball came to a rest because it desired to be in its natural state. The more inertia an object has, the harder it is to change its state of motion.

Who came first Aristotle or Galileo?

Born in Pisa, Italy approximately 100 years after Copernicus, Galileo became a brilliant student with an amazing genius for invention and observation. He had his own ideas on how motion really worked, as opposed to what Aristotle had taught, and devised a telescope that could enlarge objects up to 20 times.

What is Aristotle's theory of motion?

Summary: Basically, Aristotle's view of motion is "it requires a force to make an object move in an unnatural" manner - or, more simply, "motion requires force" . After all, if you push a book, it moves. When you stop pushing, the book stops moving.

What did Aristotle believe about gravity?

The Aristotelian explanation of gravity is that all bodies move toward their natural place. For the elements earth and water, that place is the center of the (geocentric) universe; the natural place of water is a concentric shell around the earth because earth is heavier; it sinks in water.

How did Galileo undermine Aristotle's ideas about motion?

How did Galileo undermine Aristotle's ideas about motion? Galileo postulated the idea of motional inertia, which stated that an object in motion stays in motion and vice versa, which contradicted the aristotlean view that an object needs constant force to remain in motion.

What did Galileo believe about falling objects?

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).

What is violent motion according to Aristotle?


Aristotle had natural and violent motion. Natural motion was determined by the nature of the object and how much of the four classical elements it contained. Violent motion is caused by external forces applied to the object. 3.5 Inertia is the property of objects to maintain their motion.

What did Galileo think about motion?

Galileo measured that all bodies accelerate at the same rate regardless of their size or mass. Key among his investigations are: developed the concept of motion in terms of velocity (speed and direction) through the use of inclined planes. developed the idea of force, as a cause for motion.

What are Newton's 3 laws?

Newton's three laws of motion may be stated as follows: Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it. Force equals mass times acceleration [ ]. For every action there is an equal and opposite reaction.

How did Galileo change society?

He helped created modern astronomy
Galileo turned his new, high-powered telescope to the sky. In early 1610, he made the first in a remarkable series of discoveries. While the scientific doctrine of the day held that space was perfect, unchanging environments created by God, Galileo's telescope helped change that view.

Can a ball roll forever?


The reason that a ball cannot keep going forever by simply rolling it on a surface is because of the external force of friction, which causes drag, slowing down the ball eventually making it stop.

What did Galileo value?

Galileo believed that the inertial path of a body around the Earth must be circular. Lacking the idea of Newtonian gravitation, he hoped this would allow him to explain the path of the planets as circular inertial orbits around the Sun.

When did Galileo discover the law of inertia?

Answer and Explanation:
Galileo put his findings about inertia into his book Dialogues Concerning Two New Science in 1638.

How did Galileo Galilei impact the world?

Galileo first discovered that the Moon had mountains just like Earth. He also discovered 4 of Jupiter's moons. Using his telescope, Galileo made many observations of our Solar System. He came to believe that the idea that the Sun and other planets orbited around the Earth was not correct.

What did Galileo's ideas have to do with the law of gravity?

Law of Gravity: According to history, Galileo's experiment on falling bodies largely contributed to Isaac Newton's Law of Gravity. In Galileo's experiment, he is said to have dropped balls from the Leaning Tower of Pisa. Galileo proved that objects reached the ground at the same time, independent of their masses.

Why is Galileo important?


Of all of his telescope discoveries, he is perhaps most known for his discovery of the four most massive moons of Jupiter, now known as the Galilean moons: Io, Ganymede, Europa and Callisto. When NASA sent a mission to Jupiter in the 1990s, it was called Galileo in honor of the famed astronomer.

Who discovered the moment of inertia?

It was not until the later work of Galileo and Newton unified rest and motion in one principle that the term "inertia" could be applied to these concepts as it is today.
