**ROLLER COASTER PROJECT:**

**OBJECTIVE**

**You and your team will design and construct a Paper Roller Coaster**

**DESIGN CRITERIA**

**1. ****Each roller coaster must include five design elements: a camelback, a loop, **

** wide turn and a funnel. **

**2.**** The coaster must be a complete circuit, just like a real roller coaster. **

**3. ****The marble must stay on the track through the whole roller coaster **

**4.**** The roller coaster cannot be touched during the test. In other words the tape**

** and any objects other than your hands can only be used to support the roller**

** coaster. **

**5. ****Your coaster must be stable. The track cannot move or shake when the marble**

** travels along the track. **

**PROJECT QUESTIONS**

**1. ****Draw a neat, labeled sketch of your roller coaster. Include the following terms:**

**- incline**

**- camel back**

**- loop**

**- turn**

**2. ****Write down the measurements of your Roller Coaster**

**Height First Hill : _________ m**

**Height of Inverted Loop: _________ mRadius of Loop: _________ m**

**Average time for reaching the bottom of first hill: _________ s**

**Calculation of speed at bottom of the hill: **

**3. ****Statement of conservation of energy from the top of the first hill to the bottom:**

**4. ****From the equation above, determine the velocity at the bottom of the hill:**

**5. ****How does the value of the measured speed compare to the calculation above?**

** If they are different EXPLAIN.**

**6. ****Would your results have varied if the mass of the marble had been twice as big?**

** EXPLAIN.**
