Pounding a gold coin into a different shape would probably not effect a chemical change. If, however, the pounding produced enough heat to meal the coin, some chemical change could take place.

It is a physical change because you are changing the shape of the metal.
physical change, because you are changing the physical property of the object. you are causing the change by hammering it. If you were to put some kind of chemical on it and it changed the physical property of the object that would be a chemical change.
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.
A physical change means converting how an object looks or feels. Water changed into ice or water would be a physical change. Breaking, bending, melting, evaporating are all physical changes. A chemical change would be changing an object into something you can't change back. Taking bark off a tree (physical) and burning it is a chemical change. Chemical change means burning, rusting, and combustion. I hope this helped. Nossy

A physical change because the chemical composition of the wood does not change.

hammering a nail is a physical change, this is because the nail changes shape from being long to being short and in a board for example.
It is a physical change because you are changing the shape of the metal.
Hammering hot iron into a sheet is a physical change. The process involves changing the shape and size of the iron without altering its chemical composition. The atoms in the iron remain the same, only the physical properties are altered.
