<span style="font-family: 'Times New Roman',Times,serif;">1. What safety features were in place?

The ride has over-the-shoulder restraints that lock in place once the rider is in his or her seat. Also, the restraint has a seat belt that locks itself with the seat for extra protection.

<span style="font-family: 'Times New Roman',Times,serif;"> 2. Describe the excitement level at the top, side, and bottom of the loop.

The areas where the excitement was greatest were top of the initial drop, the sides, and the bottom of the loop. There was more excitement at the bottom of the loop than the side because we felt like normal was greater at the bottom. This made it feel more dangerous, which added excitement. The side was the least exciting because we had felt normal at that moment whereas at the top we felt ready to drop 32 m.

<span style="font-family: 'Times New Roman',Times,serif;"> 3. Describe the thrill factors beside the g’s.

The thrill factors consisted of speed and direction, or otherwise, velocity. When the ride was going up the initial incline, we felt the anticipation and thrill become greater with time because of the slow speed. Other times, we felt the thrill become greater with the direction the ride was going. For example, we felt more excitement when the ride was moving downwards than when the ride was moving in the loop.

<span style="font-family: 'Times New Roman',Times,serif;"> 4. Describe the weight sensations at the top, side, and bottom of the loop. Did you feel lighter, heavier, or normal?

At the top of the roller coaster, we felt weightless like we were in space. At the side of the loops we felt normal which took away some of the excitement. At the bottom of the loop we felt the most weight sensation because that was when normal force was the most.

Evaluate:

1. #g's were within safe limits?

2. Was there correlation between #g's and excitement level? Explain, providing evidence.

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?

Other than the fact that instead of normal force the mass had a tension force, the fbds of the two were the same. This is seen in the fbd of the two at the top position of the ride. This is probably because the car was acting the same way the mass was. They were both staying in place with no angle.

2. Did the #g's correlate to the sensation of weight?

Yes, the #g's correlated to the sensation of weight because the bottom of the loop was where the number of g's was highest as with any roller coaster. As the #g's increased, so did the feeling of gravity, thus making it seem like the weight was heavier.

3. Discuss the graphs that you created and why they curve the way that they do.

The velocity vs. time graph shows the car going down the incline and then going back up. The line goes upward to show that speed is increasing as the ride was going down the initial drop. The second line goes down to show that speed decreased as the car was going up its first hill. The acceleration vs. time graph shows the car's movement when the ride had been going up the ramp. It shows that the acceleration was low because the ride was going slow. The second line shows when the ride was falling down because acceleration is high at that moment. The third line shows again the ride going up a hill. The force vs. time shows that as the ride is going up the incline every second, the force is increased. When the ride is going down the initial drop, taking less time, it uses less force. The thrill vs. acceleration graph shows that as acceleration increases, the thrill is increased as well.

<span style="font-family: 'Times New Roman',Times,serif;">Evaluate:

<span style="font-family: 'Times New Roman',Times,serif;">1. What safety features were in place?

There were lap bars that pulled down over the rider in order to keep him/her in place throughout the duration of the ride.

b. Describe the excitement level that you felt at the min and max height (if vertical), or at max speed (if horizontal)

Because the speed was constant once it accelerated to its max speed, the excitement level only lasted during the acceleration. It increased slightly as the car moved up and down, such as a feeling of weightlessness at the top, but it mostly remained the same.

c. Describe the thrill factors that may contribute to those feelings (besides the #g’s)

The aspect of circular motion contributed to the thrill factors because of the centripetal force towards the center throughout the ride. Also, the slight up and down motion added to these factors, as did the speed of the ride.

d. Describe the weight sensations at the top, side and bottom of the loop.: did you feel lighter, heavier, or normal? I felt lighter at the top, heavier at the bottom, and normal at the side, though the centripetal force was obvious.

1) Calculate Experimental Values a. Average Speed  b. Centripetal Acceleration  c. Apparent weight

2) Calculate Theoretical Values a. Average Speed  b. Centripetal Acceleration  c. Apparent weight

3) Evaluate Accuracy 4) Evaluate Safety a. #g’s The number of g's, about 1/3 of one g (9.8 m/s/s), is safe for this ride, because the average human cannot handle greater than 4g's of acceleration. Also, because this ride was controlled by a motorized track, the number of g's would not be 9.8 m/s/s because this ride was not in free fall, which is why the number 3.4 makes sense. b. Was there correlation between #g’s and excitement level? Yes, the number of g's and the excitement level are directly related because as the acceleration increases, the excitement does too.

4) Thinking about the 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? The mass on the string swung outwards during the ride because of its inertia, the tendency to travel in a straight tangential path to the circular motion. This physics concept helps to provide an explanation and support for the FBD. The diagrams of the car and the mass do not correlate because on the car itself, there was a centripetal force, along with the friction of the track beneath it, that held the car in its path of motion. The mass, however, did not have a centripetal force, but inertia that made it swing outward during the ride. b) Discuss the graphs that you created and why they curve the way that they do. The graphs above increase and plateau, which suggests and depicts the acceleration of the ride. As time passes, the ride accelerates to its max speed, which is represented by the diagonal part of the graph, and then plateaus into a straight line, which indicates that the ride has reached its max speed.  The centripetal force vs. time graph has a the same shape because the force increases as the acceleration does, while time passes. But as max speed is reached, the force remains the same for the remainder of the ride.  A similar graph illustrates the direct relationship between thrill and acceleration, because thrill increases with acceleration until max speed is reached, and thrill plateaus as well.

Evaluations:

<span style="font-family: 'Times New Roman',Times,serif;">1. What safety features were in place?

The safety feature of this ride was mainly the bar that locked in place when the rider sat down. It kept the rider underneath the bar so he or she would not fall out of the car.

<span style="font-family: 'Times New Roman',Times,serif;">2. 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 heavy because most of the pressure was on our bodies as it was going up slowly. On the way down, we felt light because we could feel ourselves lifting off of the seat. At the bottom of the first hill, we felt very heavy as normal force was greatest.

<span style="font-family: 'Times New Roman',Times,serif;">3. Describe the excitement level: on the way up, on the way down, and at the bottom of the first hill.

Like batman, the excitement level on the way up was great because of the anticipation of going down the first drop. On the way down, the excitement level felt the greatest because that was when we felt ourselves lifting off of the seats. At the bottom of the first hill, we didn't feel that much excitement because the inclines kept getting smaller.

<span style="font-family: 'Times New Roman',Times,serif;">4. Describe the thrill factors that may contribute to those feelings besides the number of g’s.

<span style="color: #800080; font-family: 'Times New Roman',Times,serif;">The thrill factors that contributed to these feelings were due to the anticipation of reaching the top of the first incline and going down the first drop. Another factor was that the car's speed was very fast on the way down the first incline.
