What is friction? How does friction relate to the roller coasters?

soccerbear — 2014-04-10 02:34:30 UTC

a friction is the action of one surface or object rubbing against another. Friction has to do with roller coaster because it affects roller coasters by slowing them down. It is also the reason why each successive hill and loop in the course of the ride gets smaller.

How do KE & PE change throughout a roller coaster ride ?

soccerbear — 2014-04-10 13:20:38 UTC

KE and PE changed throughout the roller coaster ride because when the roller coaster went up then the PE there was more the then KE but then when the roller coaster went down it went faster and there was more KE then the PE because there was more energy.

history

2014-04-13 22:22:53 UTC

roller coaster was first thought up in Russia during the 1500's, this idea was the ice slide. the idea was then transferred over to Europe in the 17th century, but made of wood instead of ice. The "scenic railways" were much longer than the ice slides and were slightly safer. Wooden roller coasters were the first roller coasters, starting in the 1920's. There are three types of wooden roller coasters; Twisters, Racers, and Out and Backs. Twisters were the first wooden roller coasters, and they are still very common. Twisters are used very often because they use up a lot less space then the gigantic out and backs, and usually cost less than the racers. Racers came after the twisters, since they required more complicated design and cost a lot more. Out and Backs probably started around the same time as racers. They require by far the most land. Out and Backs usually are great for giving air time and many consecutive drops, and that is how roller coaster starts.

Step A: Vocabulary & Friction

soccerbear — 2014-04-15 03:16:59 UTC

you get Acceleration when you start to go down a hill because you are going faster then when you going up hill.

you get Centripetal & Centrifugal force when you on going on the loops and this is what makes it not fall off of the tracks.

Momentum is the force do to the speed in mass.

you get Weightlessness when you are going really fast up or down a hill and you start to go out of your seat.

and oll of these happen when you are going on a roller coaster.
