Is mechanical weathering and physical weathering the same thing?

They are the same thing. Mechanical weather would be a subset of physical weathering. Physical weathering would be anything that reduces the physical composition of something (lets take a rock as our example.) mechanical weathering would be the result of an object of mass either abrading or cleaving the rock: sandpaper and sledge-hammers. Chemical weathering would be something like acid Photo-weathering would be from UV light
