Question

Is pressure a scalar Or a Vector quantity and why???

Answer 1

It is scalar quantity. Pressure doesn't depend on direction. Pressure only has magnitude( value) but not direction. Even though force and area are vector quatities, the division of one vector quantity over another vector quantity is not defined. So, F/A is not defined due this the direction of pressure is not defined. Hence, pressure only has magnitude but not direction. It is independent of direction.

Hope this helps you.

Answer 2

$\huge{Answer}$

Pressure is vector quantity because it does not depend on direction.

Additional Information

the force acting normally on a unit surface area is called pressure. SI unit is Newton per metre square it is also called pascal and its gravitational unit is $1kgfm^-2$
