Since Pressure = Force / Area, the SI units of pressure are:Group of answer choiceslbftN / m2NmN

To determine the SI units of pressure based on the formula $\text{Pressure} = \frac{\text{Force}}{\text{Area}}$, we can break it down as follows:

1. Break Down the Problem

   • We need to identify the units for Force and Area in the SI system.

2. Relevant Concepts

   • Force is measured in Newtons (N) in the SI system.
   • Area is measured in square meters (m²) in the SI system.

3. Analysis and Detail

   • From the formula: $\text{Pressure} = \frac{\text{Force}}{\text{Area}} = \frac{N}{m^2}$
   • This indicates that the SI unit of pressure is determined by dividing the unit of force (Newtons) by the unit of area (square meters).

4. Verify and Summarize

   • The resulting unit of pressure from our calculations confirms that it is expressed in Newtons per square meter (N/m²), which is also known as Pascals (Pa).

Final Answer

The SI units of pressure are $\text{N/m}^2$ (Newton per square meter), which is equivalent to Pascals (Pa).
