Burning of wood is considered as a chemical change. It's so because burning of wood changes the chemical composition of wood and changes it into ash whereas on the other hand cutting of wood is a physical change because it doesn't change the chemical composition of wood. In this case wood is only cut down into smaller pieces but it still remains the same but doesn't change into ash or any other thing.
