What idea of Aristotle did Galileo discredit with his experiments?

Answer Expert Verified. He discredited Aristotle’s idea that heavy objects fall proportionally faster than lighter objects. He did it by proving that force was not necessary for motion in his experiment called the Leaning Tower experiment.

What idea did Galileo disprove with his experiment in Inclined Plane?

Having no such timepiece, Galileo might have considered a study of falling objects impossible. However, Galileo was nothing if not ingenious. He had the idea that a ball rolling down an incline would accelerate in the same way as a free-falling object, but more slowly.

How did Galileo remove the mistakes in Aristotle’s theory of motion?

As we have seen, Galileo’s concept of inertia was quite contrary to Aristotle’s ideas of motion: in Galileo’s dynamics the arrow (with very small frictional forces) continued to fly through the air because of the law of inertia, while a block of wood on a table stopped sliding once the applied force was removed because …

Did Galileo invent inertia?

The law of inertia was first formulated by Galileo Galilei for horizontal motion on Earth and was later generalized by René Descartes.

What was Galileo contribution to gravity?

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.

What scientists did Galileo work with?

Galileo helped prove that the Earth revolved around the sun He became close with a number of other leading scientists, including Johannes Kepler. A German astronomer and mathematician, Kepler’s work helped lay the foundations for the later discoveries of Isaac Newton and others.

What did Galileo say about motion?

Galileo, using an Archimedean model of floating bodies, and later the balance, argues that there is only one principle of motion—heaviness. Bodies move upward not because they have a natural lightness, he says, but because they are displaced or extruded by other heavier bodies moving downward.

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 Galileo say about impetus?

Galileo on Motion. “When a mover sets a body in motion he implants into it a certain impetus, that is, a certain force enabling a body to move in the direction in which the mover starts it, be it upwards, downwards, sidewards, or in a circle.

How did Galileo influence Newton?

Galileo determined the laws of gravity and explored the laws of motion on earth. Armed with these solidified theories of dynamics, Newton proved that the force that acted on planets and moons was the same force that caused a stone to fall to the ground: gravity.

What is the difference between Aristotle and Galileo ideas about motion?

Aristotle says that the heavier things are, the quicker they will fall, whereas Galileo felt that the mass of an object made no difference to the speed at which it fell. They concluded that Aristotle was correct and it is the force of gravity that makes this happen.

What did Galileo think about falling bodies?

For thousands of years, people incorrectly believed that heavier objects fell faster than lighter ones. 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.

Do heavier objects fall faster Galileo?

It was in the nature of falling, said Aristotle, that heavy objects seek their natural place faster than light ones — that heavy objects fall faster. Galileo took an interest in rates of fall when he was about 26 years old and a math teacher at the University of Pisa.

How did Galileo discover free fall?

Galileo found that by marking a piece of parchment attached to an inclined plane that the rolling objects, regardless of the mass, would pass the tight wires at the exact same times. He also observed that the space between the lines grew at a constant rate as they moved down the plane.

What did Galileo conclude from this experiment?

Galileo thought that a ball, rolling or sliding down a hill without friction, would run up to the same height on an opposite hill. Galileo’s conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity. …

What can you conclude about the trial at which Galileo was forced to apologize for his views?

Galileo’s observations discredited the Aristotelian theory of an earth-centered solar system in favor of the Copernican “heliocentric model”. Galileo was found guilty of heresy (defiance against unorthodox methods) in 1633 and the Roman Inquisition forced Galileo to back down from his views.

How did Galileo determine acceleration due to gravity?

One of Galileo’s contributions to the founding of modern science was his study of falling objects. He turned, then, to measuring the acceleration of objects rolling down smooth ramps. The ramp “diluted” the acceleration to a value small enough to allow accurate measurements of the longer time intervals.

What force does the marble in the Galileo demonstration to eventually stop?

Eventually it slows down because of friction (a combination of air resistance and contact with the track).

When Galileo rolled a ball down an incline?

Galileo’s idea for slowing down the motion was to have a ball roll down a ramp rather than to fall vertically. He argued that the speed gained in rolling down a ramp of given height didn’t depend on the slope. His argument was based on an experiment with a pendulum and a nail, shown on page 171 of Two New Sciences.

Does a ball rolling on an incline have the same acceleration on the way up as it does on the way down?

A ball rolling on an inclined plane will not have the same acceleration on the way up as it does on the way down. Explanation: A ball rolling down on an inclined plane will have a different acceleration than a ball rolling up the inclined plane.

When a ball rolls on the floor it will eventually stop what force causes the ball to stop?

friction
