- Which statement about kinetic friction and static friction is true? (Some of the options mention a horizontal force that friction opposes. This means that a force is pulling horizontally and friction is acting in the opposite direction.) Your answer: The force of kinetic friction changes if the speed of the object decreases. The force of kinetic friction changes if the horizontal force (or forces) it opposes gets weaker. The force of static friction changes if the speed of the object decreases. The force of static friction changes if O the horizontal force (or forces) it opposes gets weaker.arrow_forwardA box of banana weighing 40.0 N rests on a horizontal surface.
