Answer» IO & RESUMEBUA PHYSICSHOMEWORK FOR 1ST QPHYSICS OLYMPIXVISUAL CLASSROOMSAAPT-NEW ENGLANDZKinematics EQUATIONS and constant accelerationIn his Dialogues of Two New Sciences, GALILEO derived the relationship between distance traveled and time as balls rolled down an inclined plane. This is often known as the Law of Falling Bodies. Interestingly, Galileo’s PROOF used classical Euclidean geometry (which would be unfamiliar to the MODERN student of textbook geometry) instead of algebra, which is what we will present here. Advanced students may derive these same equations using calculus.The BASIS for the Law of Falling Bodies is that as the ball rolls down the ramp it accelerates. As its velocity is increasing, the distance that it travels in each unit of time increases. Galileo determined this by having the rolling ball trigger bells as it rolled. |
