it is a physical change because its chemical composition does not change and no new substance is formed
Yes, it is undoubtly physical itself. The cause of easy breaking eg. after chemical detoriation of its fibrous structure by molds can be chemical. The force by which it's breaking (wind, gravity) is physical however.
Because any chemical changes occur.

Burning wood is a chemical change.
The act of cutting the tree is a physical change. However, there are chemical changes that take place as a result of cutting the tree. All plants have an ability to "feel" when they are being damaged and the plant cells around the damaged ones stiffen to attempt to prevent further damage.
Cutting a tree is a physical change. To release the carbon, there has to be a chemical change. Burning or rotting will release the carbon.
It is not a chemical change because after cutting the chemical composition remain unchanged.
Cutting doesn't change the chemical composition.
Combustion is a chemical change, so the burning of a tree will be a chemical change.
Cutting bread is a mechanical or physical change, not a chemical change.
Cutting down a tree. shredding of paper as well as same of the irreversible change
