## Motion and Forces on a Banked Curve

__Level of difficulty__: variable, algebra to precalculus

These problems deal with an object (a car, for example) navigating a circular curve at constant
speed. The radius of the curve is fixed at 10 m, but the speed and mass of the object, the
angle at which the curve is banked, the coefficient of static friction, and the gravitational field
strength can all be varied.

Two views of
the object are shown: i) overhead showing the circular path with acceleration and
velocity vectors, ii) ground level showing the forces acting on the object. As the values of
input parameters are changed, the vectors change in response. A "fric-o-meter"
gauges the ratio of the actual static friction to the maximum available static friction. This
allows the user to determine whether the object will skid off the curve or slide down to the center.
