  1. PRESSURE, FORCE AND AREA – PRACTICE QUESTIONS CALCULATOR ALLOWED 1. Find the pressure exerted by a force of 600 Newtons on an area of 30 m2. Give your answer in N/m2. 2. An object is placed on a floor. The area of the object in contact with the floor is 3 m2. The pressure exerted by the object is 15 N/m2.

  2. Pressure is measured in newtons per square metre (N/m2), but note that it is often given the special name of pascal (Pa). In order to measure how 'spread out' a force is, use this formula.

  3. Pressure = Force / Surface Area. 1. Calculate the pressure on a man’s foot when a woman who weighs 520 N steps on his foot with her heel (which has an area of 0.001 m2) with all of her weight. 2.
