what is rolling friction?
askiitians.com
2021.25
[ { "text": "dear priyajit a force which opposes the motion of any body which is rolling over the surface of another. rolling resistance, sometimes called rolling friction or rolling drag, is the resistance that occurs when a round object such as a ball or tire rolls on a flat surface. it is caused mainly by the deformation of the object, the deformation of the surface, or both. additional contributing factors include wheel radius, forward speed, surface adhesion, and relative micro-sliding between the surfaces of contact. it depends very much on the material of the wheel or tire and the sort of ground. for example, rubber will give a bigger rolling resistance than steel. also, sand on the ground will give more rolling resistance than concrete. a moving wheeled vehicle will gradually slow down due to rolling resistance including that of the bearings, but a train car with steel wheels running on steel rails will roll farther than a bus of the same mass with rubber tires running on pavement. the coefficient of rolling resistance is generally much smaller for tires or balls than the coefficient of sliding friction. please feel free to post as many doubts on our discussion forum as you can. if you find any question difficult to understand - post it here and we will get you the answer and detailed solution very quickly. we are all iitians and here to help you in your iit jee & aieee preparation. all the best. regards, askiitians experts badiuddin", "name": "", "is_accepted": false } ]
