Rotation of the Earth Accordin

Relative motion is the concept that motion does not exist for objects that move equally. This principle allowed for many of Galileo’s arguments as portrayed as Salviati. Salviati analyzes the results of several experiments and observations to prove the principal of relative motion, which serves to defeat many of the arguments against the rotation of the earth.

Most of the arguments against the rotation of the earth were in the form of experiments. Such as one experiment was that a ball, when dropped from a tower, would appear

However, in Day 2, the concept of relative motion was not used to prove that the earth rotated. The concept was used only to disprove the arguments against the earth rotating. Galileo did not attempt to convince the reader that the earth rotated but rather than to allow the possibility of rotation by eliminating the competition, Salviati states this as the purpose of the discussion. The other concepts that were included in the dialogue in Day 2 further sought to disprove Aristotelian ideas and theories about the motions of the earth, in as much the same manner as the relative motion experiments disproved the cannonball experiments.

These experiments would have appeared to have relevant conclusions to the theory involving the earth rotating. However, due to the principles of relative motion, these experiments were not relevant. Salviati showed that all motion is relative. He showed this principle by analogy. Salviati compared the motion of the earth to that of a ship. With this analogy, he was able to show that the principles of relative motion apply. He first discussed that if an object were dropped from the top of a ship’s mast while the ship was stationary and then again, when the ship was under sail, the two objects would have both land in the same spot, the object wou
