etsey preowned wedding bandsWebSince kinetic friction involves motion, the molecules in contact don’t get the chance or needed time to form such strong adhesive bonds. That’s why static friction force is greater than both sliding (kinetic) friction force and rolling friction force. Trying to slide one object across the other requires breaking these adhesive bonds. fire valley state park weatherWebIf the vehicle speedis v = m/s = ft/s = km/hr = mi/hr and the coefficient of friction between the tires and the road is μ = , the stopping distanceis d = m = ft.
