WebRolling friction is directly proportional to the normal reaction R and the load and inversely proportional to the radius of curvature. Consider the formula: f rolling = μ r R/r. where μr is called the coefficient of rolling friction. Work done by the frictional force is always negative by its definition. It is a force which opposes motion of one object over another object in contact with it In easy language,it is a force which makes moving object stop See more Friction always acts in the opposite direction of motion If we push a book on table from left to right Force of friction moves in opposite direction from right to left Similarly, if we … See more If we take a microscope and zoom in the surface of two objects, we see that both the surface have some irregularities When we try to move the … See more
