It has changed over time because Roller Coasters today are muchbigger and faster than before.
Velocity is what makes an object change position over time.
According to Roller Coaster Database (www.rcdb.com) there are 3364 roller coasters in the world, 768 of which are in North America. But those numbers change every time a coaster is built or demolished, which can happen quickly.
If you are looking for a palm sweating, fun time, the wooden roller coaster sways a lot more.
There is no answer to this question! Roller coasters are built all the time, around the world!
Roller coasters because you get more adrenaline pumped in a small amount of time when your on a roller coaster. Sports take more time to get you excited unless your like a dare devil motor cyclist which I do not advise becoming.
Sure. Your teeth might be sore, so try not to go on any shaky roller coasters (smooth ones only). But other than soreness, roller coasters should be no problem. :-)
Roller coasters are variable motion. Something that has variable motion when they have different distances and speeds in an equal period of time. Going uphill, roller coasters are sort of slow but going downhill, the roller coaster starts to accelerate. The roller coaster takes the same track every time and only goes through it once so, it has equal time periods. By traveling at 2 different speeds during equal time periods, you have variable motion.
Of course you can! My and my boy alex run that all the time
B/c roller coasters worr by winching you up the first "hill", then you're dropped, and "coast" the rest of the way. Just like any other time you ride down a hill w/o putting any more effort in.
The Tallest roller coaster is Kingda ka at Six Flags Great Adventure in Jackson New Jersey. Steel Dragon 2000 is the longest roller coaster. But i woulent count on riding that unlees you have a trip to japan planned.
Ummm. It is not that scary if you enjoy roller coasters. the first time it might be nerv racking but i think it is one of the best rides there.
