Iron has nothing to do with it. A planet cannot explode - unless something massive hits it.
The momentum and energy is transferred to the nail.
hammer is spring pushed and hits the firing pin to fire the cartridge.
You will certainly get hurt if you throw a hammer at your foot and the hammer hits your foot - unless it is a very light hammer or you are wearing substantial foot protection.
The hammer is the part that hits the firing pin when you pull the trigger.. this is just an educated guess...
The force of the hammer is much greater than the force of the nail. Gravity pulls down the hammer, hits the nail, and the nail forces up, but the force of gravity wins over the force pulling on the nail.
Kinetics
The reaction force when a hammer hits a nail is called the law of motion. This motion falls under Newton's Third Law.
