question #10
which of the following is an example of sliding friction?
○ a car sliding on an icy road.
○ a man pushing on a piece of furniture that will not move
○ a car rolling down the hill
○ a girl trying to push a wagon that will not move

Explanation:

Sliding friction occurs when two surfaces slide against each other. A car sliding on an icy road has one - surface (the car's tires) sliding over another (the icy road surface). In the other cases, the objects are either not moving (static friction) or rolling (rolling friction).

A. A car sliding on an icy road.
