Hold the nail with a pair of pliers.
Or you could be careful and hold the nail very lightly between your thumb and index finger. Hit it firmly, but not so hard that the hammer will smash your fingers down into board you are nailing. Once the nail is started, you can move your fingers and finish nailing it.
Roofers (who use thousands of nails in a day) just lightly tap the nail to set it, then drive it home with a second harder hit.
Hitting a nail with a hammer involves pushing the hammer down onto the nail to drive it into the surface. So, it is considered a pushing action.
An example of impact force is when a hammer strikes a nail. The force of the hammer hitting the nail causes an impact that drives the nail into a surface.
nail forcing the hammer
The force exerted by a hammer hitting a nail is a contact force, specifically a compressive force. This force overcomes the resistance provided by the nail and drives it into the surface.

It is kinetic energy.

You don't hammer screws. You hammer nails.The trick is to hold the nail just below the top. Then start tapping very gently. After a few taps the nail will stand up on its own. Then gently increase the strengh of the taps. This will alow your brain to get used to where the nail is. Also the nail will become stronger the further into the wood it goes.The most important thing is to be patient. Don't try to knock it in in three blows.If it's in a difficult place to hold the nail, I hold the nail in place with a small pair of pliers. Some people do hammer screws, just to put them in at the right place and then continue with a screwdriver.
The action force is the hammer exerting a force on the nail to drive it into the surface. The reaction force is the nail exerting an equal and opposite force back on the hammer according to Newton's Third Law of motion.
You should practice hitting the nail very slowly but with force. You cold also try wearing gloves for the extra protection.
When you use a hammer, the energy from your arm muscles is transferred to the hammer, which then transfers the energy to the nail or object being hammered. The kinetic energy of the hammer hitting the nail causes it to be driven into the surface, allowing you to complete the task.
The sound of a hammer hitting a nail is typically spelled as "clang" or "thud."
