The Final Jeopardy Category is: Friction Please record your wager. Click on screen to begin

The relative roughness of the two surfaces indicated by the coefficient of static friction of the surfaces (us), is one factor that influences maximum friction force, what is the other major factor. Click on screen to continue

The magnitude of the contact force between the object and the surface on which it rests. The larger the contact force (normal force), that harder it is to make the object start sliding. Click on screen to continue
