In a bicycle the rolling friction acting on the back tyre and front tyre is in which direction?
I think the answer should be back tyre has friiction in the direction of motion but i am confused in case of front tyre pls do clear that and if you have any websites which i can refer to please do inform me
If you are pedaling, then the back tire is getting friction in the direction of motion.
If you are just rolling, then both tires are getting friction against the direction of motion.
[When you are just rolling, it's like you are slightly applying brake pressure to each wheel (due to bearing friction). Imagine you lock up both your brakes. Then friction is clearly against direction of motion]
