What we did was design a roller coaster using construction paper and tape. We did some research and found a model on youtube, Paper Roller Coaster. Our roller coaster is modeled after this one. Making the ramp was fairly simple but we ran into difficulties when we came to the loop. We came to the question of how we would get the right shape for the loop to work. Our teacher, Ara, came around and looked at the video listed above and noticed that the design of the loop was sort of like snake scales, smaller pieces connected by tape. After we fixed that problem the loop worked fairly consistently. We finished the design and started gathering data. The internet was used to help us figure out what type of energy is being used to keep the marble in motion. The link under that last picture shows the best example of potential and kinetic energy.
Here are a few observations we made:
- The weight of the marble did matter
- The coster was not always consistent
Our Roller coaster is now up and running.
Good job! I like how you tracked KE and PE. You forces diagram should be something like Energy Flow since KE and PE aren't forces.
ReplyDeleteIf you could draw a diagram of the force acting on your marble at one instant during the roller coaster that would be great!
Thanks!
