Hillbilly Huckfest is Coming
the point is to not have judges, or have to run on shitty conditions, or have "small jumps"

Swatch Prime Line Munich Replay and Results
I see what you are trying to say on how it doesnt exist, and you are right in some way. The centripetal force is not like gravity force, electromagnetic force, normal force kind of force. As the force is porportional to the variation of momentum (newton) and being velocity a vector who has magnitude and direction, if you change the direction of the movement but not the speed (like in yor ball in the line example) the summatory of forces on the ball MUST be different from zero. If the ball wasn't attached to the line it would move in a straight line at constant speed ( assuming no friction and no mass variation, like in the rollercoaster blog) but if it's attached to the line it would move at constant speed and in a circular path as you described before, and you could see that the line has some tension, to keep the ball doing the circular path. That tension on the line is the centripetal force. On the roller coaster the normal force with the rails will be the centriipetal force. So in conclusion, centripetal force is the force that changes the direction of the speed, and could be a tension force ( like in a line), normal force ( like in the roller coaster) or whatever force that is acting in 90 degrees in relation to the direction of the movement
