Because the point of a sharp nail does not encounter as much resistance as a blunt one
Gravity helps to increase the force with which the hammer strikes the nail, making it easier to drive the nail into the surface. Gravity pulls the hammer downward, increasing its velocity and impact force, which helps to overcome the resistance of the nail and drive it into the material.
Nails are made with pointed tips to easily penetrate materials such as wood or metal. The pointed tip allows the nail to be driven into the material with less force, making it easier and quicker to secure two pieces together. Additionally, the sharp point helps to prevent the material from splitting when the nail is being hammered in.
The claw of a hammer works by multiplying the force exerted on it. As you apply force to the handle to pull out the nail, the design of the claw allows that force to be concentrated at the point where it grips the nail. This concentrated force makes it easier to leverage the nail out of the surface.
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.
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.
Pointed nails part the fiber of the timber. But ... this is exactly why you do not want to use sharp nails. The sharp nails push the fibers in the wood grain apart causing the wood to split along the grain. A blunt nail crushes through the fibers leaving the grain intact.

Because they do not have an edge or point that is sharp, they are less accurate and less refined. If you must fix a blunt nail, drill a much smaller hole first
The sharp point tends to work as a wedge and move the fibers off to the side. A blunt nail has to cut the fibers in order to go into the wood. This is because of pressure.

A hammer being used to pull out a nail is an example of a lever. In this case, the hammer acts as a beam with the nail as the load and the point where the hammer pivots (the fulcrum) being the point where the claw of the hammer contacts the wood. This simple machine allows the user to exert a greater force on the nail, making it easier to remove.
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.
a blunt knife has larger surface area than a sharp one. Hence force applied will have its effect on larger area causing it difficult to cut vegetables.(its just like : a nail is hammered into the wall from its pointed side....if tried to hammer on the opposite side the result will be nothing.Aki ...
the long handle provides a greater lever effect
