Question
A force of 50 N is applied to a surface 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) Explain why a smaller area gives a greater pressure for the same force 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
Understanding Pressure
Students often confuse pressure with force, thinking that a larger force always results in greater pressure, regardless of the area.
Emphasize that pressure is defined as force per unit area. To increase pressure, the same force must be applied over a smaller area.
