It is said that Galileo showed that objects of different mass fell to earth at the same velocity; that is, the gravitational force was the same.

Gravity, its not just a good idea its the law.
Galileo first theorized the idea of inertia; Newton worked further to develop itinto a law.
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.
Galileo's law
No. Galileo experimented with gravity and began developing the theory. But Sir Isaac Newton was the mathematician who proposed the inverse-square law of universal gravitation, which hypothesized that gravity is what keeps the planets in their orbs. He said that his theory was inspired by watching an apple fall from a tree.
I'm pretty sure Galileo Galileo
Dr. Mills used the Scientific laws during his research
Very little. It wasn't until Kepler that the relation between orbital period and the length of the axis of the orbit was found, and it wasn't until Newton that these relations could be derived from Newton's law of universal gravitation. Newton published his findings long after Galileo died.
Galileo
most people back then discovered that the earth rotates and they thought that if something fell from high up, it would land farther off than where it started because of the rotating earth. Galileo proved this wrong-although the earth did rotate everything on it rotated with it. he also discovered that if something fell horizontal it would keep on moving at the same speed forever.this idea became later on the first of Newton's laws, the law of inertia.
The Jovian moons. Galileo had little evidence for the heliocentric theory, which was later (in the 18th century) generally accepted as correct after the laws of motion and the law of gravity showed that the Sun is by far the most massive object in the solar system and therefore must be at the centre. Galileo did not have the other major piece of evidence supporting the heliocentric theory, which is the parallax shown by relatively close stars as the Earth moves round its orbit. Parallax is extremely small and was impossible to observe in Galileo's time, and this was used to support the idea that the Earth is at the centre. Bessel made the first measurements of parallax in the 19th century.
