When a car turns too fast, it skids away from the center and I don't understand how that's possible in terms of forces.
Background idea: The confusion came about when I was approaching a question where the net force of a car on a curve was towards the center of the curve as static friction. The question was what is the maximum speed before skidding. Easy. But wait. What happens if it does exceed that speed? Where does the skidding come from? The only force that's acting on the car is toward the center. Even if you do speed up and exceed the static friction so that you go into kinetic friction that is STILL towards the center. And the velocity of the car was tangential so there was no outwards component (by outward, i mean radially away from the center). So in order to skid, there HAD to be a force on the car away from the center. What is this force?
