i have done an experiment to find the force of friction on several surfaces.but i found that the wooden block used can move in a smaller frictional force than on plastic or glass
Will the frictional force be smaller when the same material is used(wood on wood)?but there are many crests on wood, when the wooden block moves, crests will hit crests and make the block more difficult to move.
i suppose the frictiional force(wood on glass or plastic)is smaller then that of wood on wood
