Pressure:

The normal force acting per unit area on a surface is called pressure.

Pressure = Force/Surface Area

This S.I unit newton per square metre is also known as pascal (Pa).

• Pressure is directly proportional to thrust or force: Greater The thrust; greater will be the pressure exerted by it.

• For a given us thrust pressure is inversely proportional to the surface area of an object in contact: The pressure increases when the area of contact decreases and the pressure decreases when the area of contact is increased.
