Final answer:
When driving on icy roads, the stopping distance is affected due to decreased friction. Friction is important for stopping and controlling objects in various scenarios.
Step-by-step explanation:
When driving on icy roads, your stopping distance or ability to stop will be affected. This is due to the decrease in friction between the tires and the road caused by the ice. Friction is the force that opposes motion and helps objects come to a stop. When the roads are icy, the tires have less grip on the road, resulting in a longer stopping distance.
Another example where more friction is desirable is in sports like basketball. When players dribble, the friction between the ball and the court allows them to control the ball and change direction quickly. Without sufficient friction, the ball would slip out of their hands and make it difficult to play the game effectively.
