The area of the pointed end of the nail is much smaller than that of its head. The same force produces a sufficient pressure to push the pointed end of the nail into the wooden plank.

it is because of the force acting on it...when a nail is penetrate in a wooden block it only goes from pointed side because when area is less the pressure is more because pressure is inversely prortional to area
