Why are roller coaster loops at the beginning of the ride and almost never at the end?

You need the early speed to provide centrifugal force to keep the cars nailed to the track in the loop. A loop at the end would have the cars falling off the track

Why are roller coaster loops at the beginning of the ride and almost never at the end?
energy conservation is the base of almost theory, and the roller coaster is a good physics laboratory to study physical interactions between matter and energy, becouse pontencial energy and kinetic energy, you could see this event in various type of situation, how the existence of our universe that depend of energy conservation. and others theory, for exemple quantu mechanics.
Reply:Because you need a considerable amount of momentum to get the coaster to go all the way through the loop, and the coaster is going fastest just after the first main drop. As it progresses through the ride it gradually slows down due to friction, so by the end of the ride it has much less velocity and wouldn%26#039;t be able to make it through a loop.
