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.
the answer is sir. isaac newton galileo galilei explained only the relation between motion and force
He Discovered that Earth was not the center of the solar system , Jupiter Has four moons and Venus has a face like a moon!! He also discovered the rings of Saturn. all this he just use one telescope?
Galileo was the first man to use a telescope to observe the stars and planets, and with the information he gained from this(craters on the moon, moons around Jupiter, sunspots), he was able to challenge the outdated view of the universe--which seemed to think that "the heavens" were perfect. Beyond astronomy, Galileo challenged Aristotle's concepts of motion, and discovered the principle of inertia, and his thoughts were later incorporated into Isaac Newton's universal law of gravitation.
Isaac Newton is famous for his 3 Laws of Motion.
Circular Motion
Galileo reasoned that if a ball rolled down a ramp without any friction, it would keep moving forever at a constant speed because there is no force acting to stop it. This thought experiment led him to conclude that an object in motion will stay in motion unless acted upon by an external force, a principle now known as inertia.

Galileo, then Newton.
Galileo
The concept of acceleration was first developed by Galileo Galilei, an Italian scientist, in the 17th century. He studied the motion of objects and formulated the laws of motion that describe how objects move and accelerate.
Galileo Galilei, an Italian scientist, conducted experiments that helped correct misconceptions about force and motion. He is known for his work in physics, particularly in developing the modern scientific method and making significant contributions to the understanding of gravity and the laws of motion.
No, Ptolemy did.
Galileo explained the backwatds motion of the planets
planetary motion laws
Galileo's theory of motion is principle of inertia. It is basically the same thing as Newton's law of motion since he based it on Galileo. It says that an object will remain still or keep moving in constant speed unless affected by another force.

He made a powerful telescope
