10. Roller Coasters • Watch the roller coaster from: http://www.funderstanding.com/coaster • Answer the following questions: • Why didn’t the roller coaster make it all the way through at first? • What could you change to make it work? (include all possibilities). a

11. Roller Coaster Project • Challenge: design and create a roller coaster that lets the marble travel all the way through. • Requirements: • Marble must land in the cup at the end of the roller coaster • Have at least 1 hill and 1 loop • Include a diagram with PE and KE labeled • Record the length of the roller coaster, time it takes for the marble to go through it, mass of the marble, and height of the first hill • Calculate speed of the marble, and potential energy using formulas. • Conduct 5 trials • Answer the conclusion questions • Create a poster showing your design and how you have applied your understanding of potential and kinetic energy

17. Forces on a Roller Coaster • Friction • Gravity - due to surfaces touching - the frictional force on the roller coaster is between the track and the marble. - Air resistance may also be included here This arrow represents friction. It is pushing against the movement of the roller coaster. - due to the pull of gravity to the center of the Earth. - the gravitational force pulls the marble down • Be prepared to draw arrows representing friction and gravity on your roller coaster poster This arrow represents gravity. It is pushing down on the roller coaster. What forces are acting on the roller coaster that might affect its speed?

18. A C B D Representing K.E. and P.E. At point A, a bar graph for PE and KE would look like this: What would a bar graph look like for points B, C and D? • Be prepared to label important areas for PE and KE on your roller coaster poster. • Use a bar graph to represent potential energy (PE) and kinetic energy (KE) at different places on the roller coaster.
