THE PHYSICS OF THE ROLLER COASTER
- Then move to the next height of release with the same starting radius. - Increase height of release when the ball cannot circulate a certain radius. - Record the maximum diameter of the loop that the ball can circulate corresponding to the height of release. - Repeat each height and radius 5 times. Safety precautions: - The ball bearing is small hence it is considered a choking hazard as well as other pieces. - The ball bearing is smaller than a human eyeball therefore goggles must be worn.
Secondary research
I was able to access the database showing statistics of every element of all roller coasters in the world. However, roller coaster designs vary too much nowadays I could hardly find and relevant data. Despite that, I will still present some of the data I found.
