Roller Coaster Model Build a working open track 2 loops roller coaster with a marble catch at the end . Before finalizing your design : Read the Roller Coaster Documents Measure the length of the track – pipe insulation you will be using in meters.

I. Purpose – 5 points To construct an open two loop roller coaster that will allow the marble to roll successfully from start to finish. To identify all Physics concepts related to roller coaster.

II. Background Information-15 points Write 3 paragraphs about roller coaster design References / Bibliography Web address book title Website name authors Author edition Date pages

III. Physics Concepts- 25 points Identify , Discuss , Explain , Define , Relate at least 5 physics concepts to the roller coaster design . List the 5 physics concepts’ related equations Web address book title Website name authors Author edition Date pages

IV. Materials- 5 points Styrofoam pipe insulation Tape Marble Meter stick Stop watch

V. Diagrams- 5 points Draw the perspective 2 open loop roller coaster. Draw with measurement and label

VI. Construction Procedures- 10points At least 10 steps

VII. Experimental Procedures – 10points Measure the length of the track in meters Measure the height of the starting point in meters. Measure the heights of the loops in meters. Measure the time of the marble from start to finish using a stop watch for each roller coaster in seconds Calculate the speed of the marble using speed v=length of the track / time for each roller coaster in m/s Measure the mass of the marble in grams . Convert to kg . Calculate the Kinetic energy using KE=1/2mv2 in joules M- Mass of the marble in kg, v- velocity in m/s 8. Calculate the potential energy using U=PE=mgh in joules M- Mass of the marble in kg, g=9.8m/s2, h- height of the starting point in meters
