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!
