 * Safety: What features were in place?
 * Batman has many safety features in place. When on the ride, you are locked in with a grab bar that will keep you in place. The grab bar also gives you handle bars to hold onto while on the ride. The ride has seat belts to keep the grab bar in place. There are also posters set up at the ride that explain warnings and rules to ensure that riders are safe throughout the ride.
 * 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, your weight feels the heaviest. On the way down, you feel the lightest. At the bottom, you feel normal.
 * Describe the excitement level: on the way up, on the way down, and at the bottom of the first hill.
 * On the way up, it is less exciting. Then, on the way down it is the most exciting. At the bottom there is no excitement level anymore.
 * Describe the thrill factors that may contribute to those feelings (besides the #g’s)
 * The speed, steepness, loops, and height of drops all contribute to the excitement.
 * Part B) Back at School **

c. Power needed to get up the hill 2) Calculate Theoretical Values a. Speed at bottom of the first hill  b. Acceleration down the first hill  c. Power needed to get up the hill  3) Evaluate Accuracy. > 4) Evaluate Safety  a. Calculate #g’s on the way down the hill and at the bottom of the hill

b. Were #g’s within safe limits? c. Was there correlation between #g’s and excitement level? Explain, providing evidence. 5) Thinking about Physics a) 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? b) Did the #g’s correlate to the sensation of weight? c) Discuss the graphs that you created and why they curve the way that they do.
 * Yes, the number of g's was within safe limits.
 * There was a correlation. As the g's increase, so does the excitement level. At the bottom, there is no excitement and the number of g's was smallest.
 * The mass on the string's FBD did correlate to that of the mass because they essentially moved the same way, with the addition of tension.
 * Yes, when the number of g's increased so did the weight sensation.
 * The distance v time graph curved the way it did because as time went on the rider covered more distance, first at a slower pace, but then as speed increased, at a quicker pace, thus the steepness of the graph.
 * The velocity verse time graph is constant at first because on the way up there is a constant speed but then it becomes steep because the ride accelerates down the drop.
 * The acceleration is initially zero because it does not accelerate up the incline but then the acceleration is positive because it accelerates down the trop.
 * The thrill v accelration graph curves like it does because at first it isn't that thrilling but then the thrill increases at the top of drop and on way down and then once you get down drop it lowers again.

 * Describe the safety features on this coaster
 * You wear a seatbelt, are locked in with a harness over your shoulders and there are safety signs set up all around.
 * Describe the excitement level that you felt at the top, side and bottom of the loop.
 * Top: most
 * Side: middle
 * Bottom: least
 * Describe the thrill factors that may contribute to those feelings (besides the #g’s)
 * The speed, height, and weightlessness contribute to these feelings.

Did the FBD of the car correlate to that of the mass? Why or why not? b) Did the #g’s correlate to the sensation of weight? c) Discuss the graphs that you created and why they curve the way that they do.
 * PART B) Back at School **
 * Yes, the number of g's was in the safe limits.
 * Yes, there was a correlation because there were the most g's and the most excitement at the top of the loop.
 * Yes, it did correlate becuase it was essentially the same. At the top, the FBDs looked the same because the same forces are acting on them.
 * Yes, the more g's the more weight sensation.
 * The velocity starts of quick and then at the top slows down a little and then increases again to make it around.
 * The Fc v t graph curves as it does because the centripetal force decreases and then increases again as it goes around.
 * the a v t graph looks as it does because the acceleration is first negative because it velocity is decreasing but then when velocity increases the acceleration becomes positive.
