More friction means more force is required to overcome it. This results in energy wastage. Some steps to refuce friction are-
Reducing the area of contact as friction is dire tlu dependent on the area of contact.
Lubrication. This means applying a layer of a slippery substance between the surfaces in contact. This fills up the grooves and ridges and provides extra smoothness to the objects.
Hope this helps you. And I request you to please mark my answer as the brainliest.
