What is Thrust?

The force exerted by an object perpendicular to the surface is called thrust. It is the total force acting perpendicular to the surface.

SI unit of Thrust: Its SI unit is Newton

Examples of applying thrust include activities in our daily lives, such as pushing a box or hammering a big nail into the ground. These are examples of forces acting perpendicular to the surface.

What is Pressure?

Pressure is defined as the Force or Thrust acting per unit area.

𝑃𝑟𝑒𝑠𝑠𝑢𝑟𝑒 =𝐹𝑜𝑟𝑐𝑒/𝐴𝑟𝑒𝑎 𝑜𝑟 𝑃𝑟𝑒𝑠𝑠𝑢𝑟𝑒 =𝑇ℎ𝑟𝑢𝑠𝑡/𝐴𝑟𝑒𝑎

Pressure is inversely proportional to the area on which the thrust is applied. It means that if the thrust is constant and the area is more, the pressure will be lesser. And if the area is less, the pressure will be more.

Difference in Magnitude of Pressure

SI unit of Pressure: Its SI unit is Pascal. Pressure can also be expressed as follows:

Hence,

𝑃𝑟𝑒𝑠𝑠𝑢𝑟𝑒 = 𝐹𝑜𝑟𝑐𝑒(𝑁)/  𝐴𝑟𝑒𝑎(𝑚2)

𝑃𝑟𝑒𝑠𝑠𝑢𝑟𝑒 = 1N/𝑚2

The value of 1 Pascal can be expressed as follows:

1 𝑃𝑎𝑠𝑐𝑎𝑙 = 1 𝑁/1 𝑚2
