Pressure calculations
A set of seven pressure equation questions for GCSE physics students to practise calculating pressure, force and area.
Answers are included for self or peer marking in class, as well as the formula for pressure calculations: Pressure (Nm2 (pascals)) = Force (N) ÷ Area (m2)
This worksheet is ideal for homework or as a quick learning check in class.
Example questions from the classroom worksheet:
1. A force of 300 N is exerted on an area of 0.5 m2. What pressure is applied?
2. Air pressure exerts approximately 100 000 Pa on everything at sea level. What force does air pressure exert on:
- a human, surface area 2 m2?
- a hamster, surface area 0.02 m2?
3. If a pressure of 1 kPa is applied and it exerts a force of 4000 N, what area must the pressure be acting on?
4. A skier has a weight of 800 N. If each of her skis measures 170 cm × 11cm (average), what pressure does she exert on the snow?
