The nail head gets warm because of the kinetic and thermal energy associated with the hammer coming down upon it. The formula for kinetic energy is mv2 divided by 2. So when you bring the hammer down upon the nail, you have your kinetic energy. When the hammer hits the nail, the molecules in the nail move faster. When the molecules in the nail move faster the temperature increases. Thus causing the thermal energy creating the temperature to increase. So in conclusion, that is the process of the hammer and the nail.
