I have had this doubt for a while now.
Let there be a circular banked road of some inclination with the ground.
For the sake of this question let's assume it is frictionless.
If an object with a constant velocity is travelling on it, it is in turn having a centripetal force acting on it towards the centre of its path.
This centripetal force is caused by a component of normal force which I have understood well.
But on increasing the velocity of the object, the centripetal force isn't sufficient for that radius and hence the object moves up the banked road to its corresponding radius.
However I couldn't account for any force 'up the banked road' that causes it to move that way.
Normal forces are perpendicular to that path so they don't seem to have an effect. Gravity pulls it further down so it doesn't seem like that plays a role too.
What am I missing here?
