Class 8 Physics Force and Pressure Pressure

Force acting on unit area is called Pressure ie Pressure =   Force/Area

This explains why it is easier to hammer a nail into the wall. It is because we apply a greater amount of force into a very small area of the screw head. Going by the above equation, the force is large and the area is small. So, the pressure is very high.  There are instances when you also can feel pressure - when you are having a body massage. When a person massages your body with his hands, the force applied is very high on a relatively small area of his hand. The pressure is high and there is bearable but curative pain and pressure that you feel.
