BioMedical Admissions Test (BMAT) 2025 – 400 Free Practice Questions to Pass the Exam

Question: 1 / 400

What unit is used for pressure in the formula P = F ÷ A?

Pascals

Pressure is defined as the force applied per unit area. In the formula P = F ÷ A, P represents pressure, F is the force applied, and A is the area over which the force is distributed. The SI unit for pressure is the Pascal (Pa), which is defined as one Newton per square meter (N/m²).

This means that when force is expressed in Newtons and area in square meters, the resulting unit for pressure will inherently be Pascals. The correct choice highlights the fundamental relationship between these units, aligning with established physical principles.

The other units listed—Newtons, Joules, and Watts—are measurements for different physical quantities: Newtons measure force, Joules measure energy or work, and Watts measure power. None of these units directly relate to the definition of pressure, reinforcing why the Pascal is the appropriate choice in this context.
