How did Galileo idealize his inclines to conclude that an object in motion stays in motion until it is acted on by some force?

Answer 1

Aristotle thought that when you drop 2 things with different masses that the heavier one would hit the ground first. Galileo proved him wrong by rolling two balls of different masses down an incline plane and timing them using a water clock. He found that the mass of an object does not affect how quickly it accelerates due to gravity.

Answer 2

Galileo came up with the idea of inertia. Not taking Aristotle's view that an object must have a force acting on it to keep moving, Galileo said that an object would move continuously in a straight line as long as no outside forces acted on it.

Answer 3

galelileo didnt use the word inertia but he suspected that the more mass an object has the harder gravity would push on it.

he did an experiment with 2 cannon balls of unequal weight. he dropped them at the same time they landed at the same time!

Answer 4

He took different size and colored balls to the top of the Tower of Pisa.

He dropped them all at the same time, and they all landed at the same time.

This disproves Aristotle's theory that lighter weight object fall slower that heavier weight objects.

Answer 5

Galileo studied the motion of a number of objects, such as a pendulum or balls or discs rolling down inclined planes, to observe that while such objects do not continue to move indefinitely, their motion is only slowed by friction, it is not slowed by the expiration of the original force which set it in motion. This concept was later presented much more precisely by Newton's laws of motion.

Answer 6

Yes, Galileo stated that the natural state of objects is motion
