Spend a little time "playing" with the applet. Try adjusting the speed of the car, coefficient of friction and angle of the roadway (the "bank angle"). Observe under what conditions the car will either skid inward or outward and what you need to do to counteract this.
Once you have run the applet a few times you should explore the forces acting on the car. Toggle the force button and show the free-body diagram. Again observe how the forces change with varying speed, coefficient of friction or bank angle.
Question
Explain why the free-body diagram only shows three forces acting on the car (We are ignoring air resistance here)
Question
What force or forces cause the car to round the corner and in what direction do these forces act?
Question
During an outward skid, does a force cause the car to skid outward? If so, identify this force?
