Erm... To hammer nails?
The function of a hammer is best described by its relationship to the nail. If it is indeed servicing the nail with proper force, the nail will succumb to the pressure and it will get pounded deeper and deeper into a hole. In short, the hammer pounds really hard. And a good hammer leads to a good nail.

I will strike the nail with the hammer. I strike the nail with the hammer. I struck the nail with the hammer. I have struck the nail with the hammer.

When you hit a nail with a hammer, the force is applied at the point of contact between the hammer and the nail. This force drives the nail into the surface it is being hammered into.
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.

After the hammer hits the nail, its momentum is transferred to the nail causing it to move. Momentum is conserved in the system, meaning that the total momentum of the hammer and nail before and after the collision remains the same.
