Question

why is rolling friction inversely proportional to radius ​

Answer 1

Answer:

the rolling frictional force is inversely proportional to radius 2. it increases with area of contact. FOR A BIGGER WHEEL RADIUS IS GREATER. THE AREA OF CONTACT IS GREATER.SO FRICTION IS GREATER.

Answer 2

Answer:

rolling friction force is inversely proportional to radius. it increases with area of contact ..the area of contact is greater . so friction is greater. but from 1st point the friction should be less if the radius is greater
