Question
A force of 50 N is applied to an area of 2 m². Calculate the pressure exerted on the surface Explain your answer using Pressure on a surface (physics only) and pressure.
Answer
The pressure exerted on the surface is 25 Pa.
Explanation
A strong answer should address (Physics only) Use the equation pressure = force normal to a surface divided by area of that surface directly. Use the context of Pressure on a surface (physics only) within Pressure and pressure differences in fluids (physics only), then state the relevant forces or motion reasoning with units where needed. The answer is correct when it names the key physics quantity, keeps force and pressure distinct, and links the conclusion back to the approved learning objective.
Common mistake
Misunderstanding Pressure Calculation
Students often confuse the formula for pressure, mistakenly using pressure = area / force instead of pressure = force / area.
Remember that pressure is defined as force applied per unit area. Always use the correct formula: pressure = force normal to a surface divided by area.
