How does a roller coaster get from beginning to end?

So it gets pushed or shot out onto the track and then the rails pull it up hills so it can cat momentum, of have that new special thingy where it shoots you forwards like a gun, and then it goes to the end.

This answer probably isn't 100% correct, and I'm sorry for that.

Have a luvely day!

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."
