compared it with the distance the ball had travelled. The difference and ratios of these weighs gave Galileo the times’ differences and ratios.
What Results Did He find?
By doing experiments with balls on inclined planes, Galileo showed what he thought was a law of motion, that is, S = 1⁄2 at 2.
o “S” is distance.
o “a” is acceleration. o “t” is time.
In other words, the distance travelled by the ball is proportional to the square of the time. If we double it, then the ball goes four times as far because gravity accelerates it constantly. In this way, Galileo discovered that the ratio of times to travel two different distances remains unchanged if we change the slope and acceleration increases. Aristotle, on the other hand, would have predicted that the ball’s velocity was constant: that is, double its time in transit, and you double its distance.
