Question

Why is rolling friction inversely proportional to the radius of the rolling cylinder or wheel?

Answer 1

The force of friction when a object roles over opposite object it remains same

Answer 2

Answer:

Hey guys I m Tanishk Dev Singh. pls follow me.

Explanation:

Rolling friction is inversely proportional to radius.

because as the radius increases there will be more area of tier or wheel.

we know that pressure is equal to Force/Area.So due to more area there will be less pressure.As a result force of friction reduces.

I know u will have confusion in it.I also have before 1 year

see Rolling friction composed of two things

1.. The force that opposes the body to come out of the depression.Always at microscopic level depressions are created when body rolls over another body.

2 ...The interlocking between the particles.
