Thrust per unit area is called ______.
Pressure
Pressure is correct.
In mechanics, thrust is the force that acts perpendicular to a surface. When this perpendicular force is spread over a surface, the quantity that measures how concentrated the push is on each unit of that surface is called pressure. The defining relation is \(P = \dfrac{F}{A}\), where \(F\) is the thrust and \(A\) is the area.
The SI unit of pressure is the pascal (\(1\,Pa = 1\,N/m^2\)). Mass is a measure of the amount of matter and force is an interaction; neither is a per-area quantity. Area itself is only the denominator in the ratio, not the ratio.
