Question

we do not need wheels in rolling friction true/false
​

Answer 1

Rolling resistance is usually less than static friction because the surface of contact is very very small in real life so the net normal force is also small and not enough like the static friction to prevent the body from sliding and keep it unmoved and static friction also increases with the increase of the external .....

so it is false

Answer 2

Answer:

false

Explanation:

in rolling friction one thing rolls over another and it is impossible for any object to roll without wheels
