Two identical cars, one on the moon and one on the earth, have the same speed and are rounding banked turns that have the same radius r. There are two forces acting on each car, its weight mg and the normal force FN exerted by the road. Recall that the weight of an object on the moon is about one-sixth of its weight on earth. How does the centripetal force on the moon compare with that on the earth?
(a) The centripetal forces are the same.
(b) The centripetal force on the moon is less than that on the earth.
(c) The centripetal force on the moon is greater than that on the earth. |
