How does a hammer work?

When the hammer strikes the nail it is travelling fast and because the head is very hard, it doesn't absorb the blow. This means the kinetic energy is instantly transferred to the nail. The resultant force is large enough to overcome the friction of the material you're driving the nail in to.
