When a wheel is rolling on a level, what is the direction of frictional force between the wheel and the road ?

A

backward direction

B

forward direction

C

depends on speed

D

cannot say

Text Solution

Verified by Experts

The correct Answer is:
b
The motion of the point of contact of weel with the level road is directed backwards tangentially Therefore frictional force must be in forward direction .
