We generate friction almost every day when you think about it because judging by its definition, friction is the force resisting the relative motion of solid surfaces, or any other types of surfaces like fluid layers, or when material elements sliding against each other. So, it can occur countless times during the day. But can you define it in its entirety? Take our quiz and find out now.
