Question

why does a rolling friction stop after moving some distance automatically.

Answer 1

Answer:

I don't know the answer

Answer 2

Answer:

your answer is here !

Explanation:

rolling ball stops after moving some distance due to friction force act opposite direction of motion of ball . you can see in figure .

Let any rolling ball of mass (m ) is moving with velocity v ,

normal reaction on ball (N) = mg

due to motion , friction force appears on contact surface and start to opposing motion of rolling ball .

hence,

fr = uN = umg act on contacting surface, so, after some time due to friction force rolling ball comes rest .
