 * Evaluate Safety:**
 * 1) Calculate # g's on the way down the hill and at the bottom of the hill.
 * # g's = a/g
 * # g's = 3.41/9.8
 * # g's = 0.35
 * 1) Were # g's within safe limits?
 * No because the number of g's was less than 1 which is the minimum number of g's. Though this was obviously a source of error since the ride has to be safe in order to be running at six flags.
 * 1) Was there correlation between # g's and excitement level? Explain, providing evidence.
 * Yes, there is a correlation between number of g's and excitement level, since as one increases so does the other. The number of g's is greatest as the car approaches the bottom of the hill which is also when the ride is most exciting.


 * Thinking About Physics:**
 * 1) 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 behaved essentially the same as the car. The FBD correlated greatly since the same forces acted upon the objects as they followed the same path, though obviously the mass on the string has the addition of tension which the car does not.
 * 1) Did the # g's correlate to the sensation of weight?
 * Yes, as the number of g's increases, the weight sensation also increases. The sensation of weight can either be that of heavier or lighter weight, just a weight that isn't your actual weight.
 * 1) Discuss the graphs that you created and why they curve the way they do.
 * Distance vs. Time graph appears as it does because as time increased, the car covered more distance at a faster pace hence the increasing steepness of the graph.
 * Velocity vs. Time graph appears as it does because the car increases at a constant velocity up the hill and then speeds up very quickly as it goes down the hill.
 * Acceleration vs. Time graph appears as it does because there is no acceleration as the car is pulled up the hill and only becomes positive acceleration when it goes down the hill as the velocity is increasing.
 * Thrill vs. Acceleration graph appears as it does because the thrill/anticipation increases as going up the hill and then is highest when going down the hill and continues to decrease as approach bottom of the hill.

Activity B: Batman

 * Evaluate Safety:**
 * 1) # g's were within safe limits?
 * No the number of g's were not within safe limits. The number of g's that a person can withstand are between 1 and 4 g's, but according to our calculations the number of g's was only 0.94. Clearly, this is a source of error on our part though, since more than likely Batman does have a number of g's within the safe limits; although 0.94 is within 10% error of 1 so can assume safe.
 * 1) Was there a correlation between # g's and excitement level? Explain, providing evidence.
 * Yes, as the number of g's increases, the excitement level also increases. For example, the most amount of g's (or highest acceleration) is at the top of the loop, which is also the most exciting part of the loop.


 * Thinking About Physics:**
 * 1) 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 behavior of the mass on the string was essentially the same as that of the car. The FBD greatly resembled each other since, with the exception of the tension of the mass on the string, the two items had the same forces acting upon them as they followed the same path.
 * 1) Did the # g's correlate to the sensation of weight?
 * Yes, the greater the # g's, the more of a weight sensation was felt. For example, the most amount of g's are at the top of the loop which is also where the rider feels the most weight sensation as being weightless.
 * 1) Discuss the graphs that you created and why they curve the way that they do.
 * Velocity vs. Time graph appears as it does because the car starts at a high velocity but decreases as it rounds up the loop, reaching its lowest at the top, and then increasing velocity once again as it goes back down the loop.
 * Centripetal Force vs. Time graph appears as it does because the centripetal force decreases as the car rounds the top of the loop and then increases again as the car rounds back to the bottom of the loop.
 * Acceleration vs. Time graph appears as it does because acceleration is negative when the velocity is decreasing and then becomes positive again once the velocity is increasing.
