 * //Evaluate//**
 * What safety features were in place?
 * There were individual lap bars, fin brakes, and an evacuation platform.
 * Describe the weight sensations on the way up, on the way down, and at the bottom of the first hill: did you feel lighter, heavier, or normal?
 * On the way up, we felt heavier, and on the way down, we felt lighter, but just barely.
 * Describe the excitement on the way up, on the way down, and at the bottom of the first hill.
 * Going up the hill was far less exciting than traveling down the hill, though the feeling of excitement did increase the farther and farther we got up the hill.
 * Describe the thrill factors that may contribute to those feelings (besides the # of g's).
 * Seeing the drop at the top of the hill and the apprehension of the ride down definitely contributed to the excitement.

Speed at bottom of first hill:
 * //Calculate Experimental Values//**

Acceleration down the first hill: Power needed to get up hill: Speed at bottom of first hill: Acceleration down the first hill: Power needed to get up hill: //Evaluate accuracy of the three calculations above.//
 * //Calculate Theoretical Values//**


 * //Evaluate Safety://**
 * Calculate the #g's on the way down the hill and at the bottom of the hill
 * [[image:Screen_shot_2012-05-25_at_12.30.02_PM.png]]
 * Were the #g's within safe limits?
 * Yes, very safe.
 * Was there a correlation between #g's and excitement level? Explain, providing evidence.
 * Yes - see the thrill vs acceleration graph above for evidence.


 * //Thinking about Physics//**
 * Explain the behavior of the mass on the string. Did the FBD of the car correlate to that of the mass? Why or why not?
 * The mass on the string should have correlated to it because it functions like an aplomb.
 * Did the #g's correlate to the sensation of weight?
 * Yes - as the acceleration increases, so does the weight sensation.
 * Discuss the graphs you created and way they curve the way that they do.
 * Distance vs Time
 * At first, distance is covered gradually over time. Then, it's barely covered at the top of the hill. As the train travels down the hill, it picks up speed and covers more distance.
 * Velocity vs Time
 * Velocity is constant as the train travels up the hill, and as it goes down the hill, acceleration rapidly increases.
 * Acceleration vs Time
 * There is no acceleration as the train travels up the hill, but as it goes down, acceleration increases.
 * Thrill vs Acceleration
 * Thrill increases as acceleration increases.

 * Graphs**


 * //Evaluate//**
 * What safety features were in place?
 * There were safety straps, a platform for feet, and an evacuation platform.
 * Describe the weight sensations on the vertical loop: did you feel lighter, heavier, or normal?
 * We felt lighter at the top than we did at the bottom.
 * Describe the excitement that you felt at the top, side, and bottom of the loop.
 * It was very exciting throughout, especially when we had just entered the loop.
 * Describe the thrill factors that may contribute to those feelings (besides the # of g's).
 * Seeing how fast the ride went before we got on it was thrilling and made the ride seem more exciting. Knowing that the loop was coming also contributed to this.


 * //Thinking about the Physics//**
 * Explain the behavior of the mass on the string. Did the FBD of the car correlate to that of the mass? Why or why not?
 * Yes - it behaved like an aplomb.
 * Discuss the graphs that you created and why they look the way they do.
 * Centripetal Force vs Time
 * The centripetal force decreases as you near the top.
 * Velocity vs Time
 * Velocity decreases as you go up to the top, is constant at the very top, and increases as you leave the loop.
 * Acceleration vs Time
 * The acceleration vs time graph matches up to the velocity vs time graph.

 * //Evaluate//**
 * What safety features were in place?
 * Locking Cage Door
 * Describe the excitement around the circle.
 * As the acceleration increased, the ride became more nauseating.
 * Describe the thrill factors that may contribute to those feelings (besides the # of g's).
 * The thrill factor was that it spun around a lot.

//**Calculate experimental values**:// Average speed Centripetal acceleration Apparent weight

Theoretical period: .117 (7 rpm) (http://www.zamperla.com/en/product/141/tea-cup.html) Average speed Centripetal acceleration Apparent weight
 * //Calculate theoretical values//**


 * //Evaluate Safety//**
 * Was the number of g's within safe limits?
 * Yes - again, it was very safe. 0.815 g's.
 * Was there a correlation between # of g's and excitement level? Explain, providing evidence.
 * The # of g's hypothetically remained constant throughout the ride, so it's hard to say. Certainly the ride was most exciting when it was at its fastest - when it had the most g's - but there was only a short time that it was not at that speed (when it was building up to that speed).


 * //Thinking about the Physics//**
 * Explain the behavior of the mass on the string. Did the FBD of the car correlate to that of the mass? Why or why not?
 * The FBD and the teacup had the same FBD, except for the centripetal force. There was no centripetal force acting on the mass on the string, while there was on the teacup.
 * Discuss the graphs that you created and why they look the way they do.
 * Centripetal Force vs Time
 * The centripetal force increases as the teacup spins.
 * Acceleration vs Time
 * The ride increased velocity when it started, kept a constant velocity in the middle, and decreased to a stop at the end.
 * Thrill vs Acceleration
 * The thrill is larger with a larger acceleration.
