Okay, so i understand that circular acceleration and force point to the middle of the circle. Now let's say a roller coaster is doing a loop, at the top of the circle, why wouldn't the roller coaster just fall down? force of gravity is pointing down, the Fc is pointing down. What force is keeping the roller coaster from falling down? and why don't we ever lable this force on free body diagrams?
THANKS!
