Part 2: Design and construct your rollercoaster (30 mins)
1. Groups should first make a rough sketch of their design before they start to build the track.
2. Construct the rollercoaster and test to see if it works. Revise design and keep testing until the marble completes the loop.
3. Sketch successful track design and label where the potential energy and kinetic energy are at their maximums. Label the height that the marble starts from as well as the slope of the initial downward track.
4. Calculate the maximum potential energy and use this to calculate the velocity when the marble enters the loop. Start the marble at an even higher height and see what happens to the velocity. Change the slope and see how the velocity is affected.
