A chain.
Yes. Roller coasters are getting much more faster and lot stronger than before. Every single day roller coasters are getting upgraded to make it even more terrifying. In every year, roller coasters are getting a lot scarier and way much more terrifying and it could be possible for roller coasters to get stuck up there but roller coasters still can get down once it was fixed.no
The ringracer, worlds fastest roller coaster, goes up to 135 mph.
To make it more intense.
They are fine you won't get fat or something like that. Just be careful some old roller coasters can shake you up though.
Gravity...
I looked it up and saw 634.
At Cypress Gardens a boy stood up on a wooden roller coaster and died
because trumps and farts make the ride so much better and lets gravity waken
Roller Coasters are generally moved up the initial hill by electric motors, then dropped, when they are powered completely by gravity. Others use electromagnets to accelerate without gaining initial height.
you can use it to find your angle of elevation idk it is just a question that teachers came up with to make ypu work
No, they travel with gravity after their travel up a lift hill or after a launch.
Potential energy is what make the coasters go down and flip and go fast and does all that wacky stuff. The potential energy builds as you go up on a hill the first time. It's potential energy all the way until you drop. From there it's all just kinetic energy. Without all the potential energy the coaster wouldn't even go anywhere.
