WebRolling friction is an important type of friction to understand because of the presence of many rolling objects around us like car wheels and windmills. Mathematically, it can be represented as. Fr = μrN. Where. F is the magnitude of rolling friction, N is the normal force on the object, μr is the coefficient of rolling friction. WebThe acceleration, velocity and time taken by a body sliding along a smooth horizontal surface can be obtained by putting µk = 0 i.e. a = g sin θ , v = √2glsinθ and t = √2lgsinθ. The force to move up the plane with uniform velocity is F = mg sin θ. Pulling force F = Wsinφ / cos (θ - φ) and pushinf force F = Wsinφ / cos (θ + φ ...
