what is rooling friction
Answers
Answer:
Rolling friction is the force resisting the motion of a rolling ball or wheel (a curved surface). This type of friction is typically a combination of several friction forces at the point of contact between the wheel and the ground or other surface.
It is the weakest type of friction (compared to static and sliding friction). This is the reason that wheels and ball bearings facilitates motion.
W is some vertical load on the axle, F is some towing force applied to the axle, r is the wheel radius, and both friction with the ground and friction at the axle are assumed to be negligible and so are not shown. The wheel is rolling to the left at constant speed.
Answer:
rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body rolls on a surface.
