Assessment
If the rollercoaster was shaped like the drawing, list the numbered positions in order from where the marble has the fastest speed to where the marble has the slowest speed.
Suppose you measure the speed of the marble at the lowest place on the rollercoaster by repeating the activity on two tables of different heights as shown above. Would your results be any different?
Suppose you have a rollercoaster that does a loop as shown in the diagram. Describe what happens if you start the marble at each of the three places shown. Your answers should state whether the marble makes it around the loop or not and anything else you think might happen along the motion.
Sketch a graph showing potential energy versus distance and kinetic energy versus distance for the marble rolling down the rollercoaster shown on the right. Assume there is no friction.
