For the normal force in the drawing to have the same magnitude at all points on the vertical track, the stunt driver must adjust the speed to be different at different points. Suppose, for example, that the track has a radius of 2.24 m and that the driver goes past point 1 at the bottom with a speed of 28.3 m/s. What speed must she have at point 3, so that the normal force at the top has the same magnitude as it did at the bottom?

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
