Question
A hydraulic press exerts a pressure of 5000 Pa on a surface area of 0.2 m². Calculate the force exerted by the press on the surface Explain your answer using Pressure on a surface (physics only) and pressure.
Answer
The force exerted by the hydraulic press is 1000 N.
Explanation
A strong answer should address (Physics only) Calculate force from pressure and area 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
Common Mistake in Calculating Force
Students often confuse the formula for calculating force from pressure and area, mistakenly using pressure = force / area instead of the correct formula.
Remind students that the correct formula is force = pressure × area. Encourage them to practice rearranging the formula correctly.
