Question

Force per unit area is called.

• A. Upthrust.
• B. Buoyant force.
• C. gravity.
• D. Pressure.

Answer 1

The correct option is D

Pressure.

1. Pressure is defined as force per unit area.
2. The standard unit for pressure is the Pascal, which is a Newton per square meter.
3. Mathematically, it can be written as $Pressure\left(P\right)=\frac{Force\left(F\right)}{Area\left(A\right)}=\frac{N}{m}=Pascal$
4. For an object sitting on a surface, the force pressing on the surface is the weight of the object, but in different orientations, it might have a different area in contact with the surface and therefore exert a different pressure.
   Hence, the Correct option is D
