## What is the idea of Aristotle and Galileo 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. Aristotle’s theory of motion was different than Galileo’s. Explain what causes an object to change its motion.

### Who is correct Galileo Aristotle?

They concluded that Aristotle was correct and it is the force of gravity that makes this happen. However, Year 5 also found out, from watching a clip on the moon, that when you take gravity out of the situation Galileo’s theory is correct and both a hammer and a feather fell at the same speed. So they are both correct!

#### Why did Galileo challenged Aristotle?

Galileo challenged the Aristotelian theory of gravity too. Aristotle had taught that material objects are comprised of four elements: earth, air, fire, and water. Each of these elements has its rightful place in a natural hierarchy: earth belongs at the bottom, water on top of that, air above water, and fire above air.

What theory of Aristotle did Galileo disprove?

theory of gravity
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 idea of Aristotle did Galileo discredit?

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.

### How did Galileo undermine Aristotle?

4. How did Galileo undermine Aristotle’s ideas about motion? Galileo formulated the law of inertia, which showed that a uniform force– in this case, gravity–produced a uniform acceleration.

#### How did Galileo prove inertia?

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 proof of this idea was that if a ball rolled down one ramp, its inertia would cause it to roll up an opposite ramp of equal height.

What was the difference between Aristotle and Galileo?

Galileo Galilei, lived in Pisa home of the tall leaning tower — just right for an experiment challenging Greek philosopher Aristotle. Aristotle said that a heavier object falling from the same height, at the same time, would travel faster than a lighter object. Galileo disagreed.

What did Aristotle teach us about the physics?

The Physics of Aristotle versus. 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.

## Who was the Roman cardinal who called Galileo to an audience?

Galileo himself was called to an audience with Cardinal Robert Bellarmine, a leading theologian and member of the Roman Inquisition, who admonished him not to teach or defend Copernican theory. (The details of this episode are far from straightforward, and remain disputed even today. See Shea and Artigas 2003; Fantoli 2005.)

### What did Galileo teach us about the physics of motion?

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.
