AND when shape of an object is spherical it undergoes rolling friction and when the shape is a flat surface the moving object undergoes sliding friction which is greater than rolling friction
Class : Class 9
But if the shape of the object is streamlined then then the force of friction exerted on it will be less
Class : Class 6
shape of the body affects the drag friction also sliding and rolling friction would be same if shape did not matter.
