Roller Coaster: Task 2- Video Clip 1

I learned that most of the time the roller coasters are doing the spine-tingling stunts they are all applied solely because of gravity, potential energy, and kinetic energy. At the beginning of the ride, the roller coaster is lifted by a chain, which slowly pulls the roller coaster up the first hill, storing all the potential energy it needs. When the roller coaster gets to the top and is about to plunge down the first hill, that potential energy turns into kinetic energy.

Roller Coaster- Conclusion

• The more energy a roller coaster has at the beginning of the ride, the more successful the ride. That means it needs to begin with a lot of potential energy.
• What factor do you think affects the amount of potential energy the roller coaster will have? The height of the first hill determines the amount of potential energy
• What do you think is the safest way to "come down" from the first hill? The safest way to come down the first hill is to have a smooth, low-sloped hill
• How do you think the roller coaster should exit from the first hill? It should exit with a clean low path to carry all the momentum so it won't crash
• What do you think the height of the second hill should be? The second hill should always be low enough so that it isn't higher than the first hill but still can pass on enough kinetic energy
• What shape do you think the loop should be? (Parabola, elliptical, square...etc) the loop should be elliptical to give the passengers excitement and a faster spin so the roller coaster won't slow down and/or stop and/or crash

Roller Coaster: Task 3- part 2

Roller Coaster: Task 3- part 1

• The height of my first hill was 80 meters
• the shape of the my first hill was was smoot slope
• the exit path was a low slope
• the height of my second hill was 70 meters
• My loop was elliptical that was 35 meters high
• the arrows indicate the maximum potential and kinetic energy levels

Roller Coaster: Task 1- Video Clip 3

 The max amount of potential energy is collected on the first hill of the roller coaster. That potential energy is then converted into kinetic energy at the bottom of the hill, which is the max amount of kinetic energy. On a loop the potential energy is stored at the highest point, which is released at the bottom.

Roller Coaster: Task 2- Video Clip 2

I learned that on a roller coaster, all the kinetic energy u need is all there by the time you reach the bottom of the first hill. The only thing is that the rest of the loops and hills and turns have to be lower than the first in order for the roller coaster ride to continue without stopping. If that was the case then the ride would come to an end very shortly, without making it back to the starting point.
