Pressure is defined as the force per unit area. Mathematically, it is expressed as:

Pressure=ForceAreaPressure=AreaForce

Where:

  • PressurePressure is the pressure applied,
  • ForceForce is the force applied, and
  • AreaArea is the surface area over which the force is distributed.

To increase pressure while exerting the same force, you can achieve this by reducing the area over which the force is applied. The formula shows that pressure is inversely proportional to the area. So, if you keep the force constant and decrease the area, the pressure will increase.

For example, imagine pressing your finger against a surface. If you use the same force but concentrate it on the tip of your finger (reducing the area of contact), you will feel a higher pressure. On the other hand, if you spread the force across your entire hand (increasing the area of contact), you will experience lower pressure.
