Question

Is pressure a scalar or vector?

Answer 1

Scalar

Scalar quantity only has magnitude and no direction.

Vector

Vector quantity has both magnitude and direction

Pressure

1. Pressure is the ratio of force to area.
   $Pressure=\frac{Force}{Area}=\frac{F}{A}$
2. SI unit Pascal (Pa).
3. It is a scalar quantity that is, it has magnitude and no direction, it acts in all directions

Example: Force inside a closed container acts in all directions but the pressure is the same everywhere

Hence, pressure is a scalar quantity.
