Hammering wood together to build a playhouse is a physical change because it involves altering the arrangement of the wood pieces without changing their chemical composition. The wood remains wood, and its properties do not change at a molecular level; only its shape and structure are modified. This process exemplifies how physical changes can create new forms or structures from existing materials.
When you throw a penny and a piece of wood into a bowl of water, the penny sinks because it is denser than water, while the piece of wood floats due to its lower density. The buoyancy of the wood allows it to stay on the surface, while the penny displaces water equal to its volume until it reaches the bottom. This demonstrates the principles of density and buoyancy in a simple experiment.
A flat piece of wood is called a board.
A thick piece of wood is called a plank. It is a long, flat piece of wood that is often used in construction or woodworking projects.
A piece of wood siding is called a clapboard or a plank.

Physical.
It is a physical process.
It would be a physical change because you are changing the shape of the wood not the chemical composition of the wood. However, you could possibly create a chemical change if you could hammer hard and long enough to burn the wood. Not likely, but it is possible.

just be good with wood and hammering nails
A physical change because the chemical composition of the wood does not change.
If one's wrist is broken, one needs to treat it. Bones will heal themselves, but they need to align properly. A piece of wood is needed to make sure that the bones line up properly to recover fully in strength, movement and sensitivity.
No, no reaction takes places.
The wood largely consists of trachieds. these are lignified cells attached to each other by calcium pectate, a substance which works as a cementing material. Therefore due to elasticity of the trachieds, it is difficult to get powder of it by hammering.
A piece of permineralized wood is called petrified wood. It forms when wood becomes fossilized by minerals replacing the organic material over time, resulting in a stone-like appearance while retaining the structure of the original wood.
