Is pressure a scalar or a vector quantity?
Pressure is the force acting in all directions on an area while force is a push or pull in a direction. The term pressure is applicable for bulk materials (like water) where individual particles are considered as soft. Pressure does not have any unique direction.
When a bomb blasts, it effects in all directions in air whereas if a running car hits, it effects in the specific direction only. A parameter effecting in all directions uniformly is considered as if it is a scalar. The pressure acts to all the directions uniformly.
The formula for pressure is,
P= F/A , is only the magnitude relation, not direction.
Pressure is the ratio of force and vector area..
A vector quantity can be defined by giving both magnitude and direction.
Pressure has only magnitude but no specific direction as it acts in all directions.
So, pressure is a scalar.
