Lubricants are the material or subtance that are used to reduce friction

Sometimes friction between two objects are so much that they can't even move. So lubricants are applied between them to reduse the friction. lubricants are usually liquid because they can get filled easily between the ups and downs in a rough surface and reduce the friction. remember lubricants only reduce the friction they don't vanish it, there is still some roughness and adhesion between them. hope it helped. thanks
