These principles made a moving Earth plausible, and also provided a basis for analyzing the motions of ordinary bodies. In his Discourses on Two New Sciences (1638), Galileo derived his laws of falling bodies: 1) speed of a falling body increases in proportion to the time elapsed: v = at. 2) distance travelled in free fall increases with square of the time elapsed: d=1/2at 2 . 3) projectiles follow parabolic trajectorie s....
