Which type of friction involves the tire and road surface?

Rolling friction is the type of friction that involves the tire and the road surface during motion. When a tire rolls on a surface, it does not slide but rather experiences a form of resistance known as rolling friction. This is due to the tire's deformation as it makes contact with the ground and the subsequent recovery of the tire's shape once it rotates.

Rolling friction is generally less than static or kinetic friction, which is significant for vehicles since it allows for smoother movement and better fuel efficiency. It's essential for law enforcement driving as understanding this type of friction helps officers maintain control of their vehicles during pursuits or evasive maneuvers, especially in adverse conditions.

In contrast, kinetic friction pertains to surfaces sliding against each other, while static friction refers to the force that resists the initiation of sliding motion. Gas friction would not apply in this context as it typically refers to the resistance met by objects moving through a gas, which is unrelated to tire-road interactions. Understanding these distinctions is crucial for safe and effective vehicle handling during law enforcement operations.
