Question

why does a car slide when it rolls over an icy patch on a road? A. cars have more momentum on icy surfaces. B. there is less friction between the cars tires and the ice than between the car tires and the road. C. there is more friction between the cars tires and the ice than between the car tires and the road. D. cars have less momentum on icy surfaces.

Answer 1

The answer is B
because if you compare a regular road and ice... ice is smoother and therefore has less friction 

Answer 2

B) because a road is usually covered in rocks which increases the friction, but since its now covered in ice which is usually a smooth surface is has less friction leading to the car sliding. Also if the top of the ice has melted it may hav left behind water and hitch is a lubricant and reduces friction
