Question
Why does a sharp nail easily penetrate wood, but not a blunt nail?
✓

Answer

We know that Pressure is inversely proportional to area. So, smaller area will exert more pressure, thus a sharp nail has small area that comes in contact with the object, so more pressure can be applied on the object.
