Question

What are the SI units of (a) pressure and (b) thrust?

Answer 1

We know, $Pressure=\frac{Force}{Area}$

(a) Pressure is defined as the thrust acting per unit area on an object. It is denoted by the letter $P$
So, the unit of pressure is $N{m}^{-2^{}}$which is called Pascal (Pa).

(b) Thrust is the force acting perpendicular to the surface of an object.

Since, thrust is the perpendicular force acting on a body, its unit is Newton (N)
