Central Challenge Students observe a steel ball rolling down an inclined ramp, then across a horizontal track, and finally as a projectile off the end of the ramp onto the floor. If you give the cart a gentle push up the incline, the cart will roll upward, slow and stop, and then roll back down, speeding up. 1 Purpose In this experiment, rotationalmotion will be examined. F r = c W (1) where . Likewise, the velocity graph does not give you the actual position of the object, just how it is changing. Complete reports will include the terminology and the mathematics relevant to the problem at hand. Prior to students arriving, I have a complete set of these materials at each lab station around the room. For example, Galileo hypothesized that objects experienced uniform acceleration due to gravity. Objective . Projectile motion, for our purposes, is the motion of an object that has been launched and then is subject to only the force of gravity and the force of air friction. Typically, during the first part of the motion the bowling ball slides along the lane, since its rotational speed does not match with the linear velocity of the ball. encourage them to report on what they observed, share their discoveries, and pose  A microscopic view of these surfaces in relative motion reminds us that each the Surfaces — Sliding motion versus rolling motion can affect the coefficient of  3. • Galileo studied motion of objects rolling down an inclined plane with smooth surfaces. Newton's first law of motion introduction.
