Science · Grades 8–12
Pressure and force
Force is perpendicular to the surface; pascals are newtons per square metre.
The key idea
Force is perpendicular to the surface; pascals are newtons per square metre.
p = F/A
Worked examples
A perpendicular force of 615 N acts over 5 m². Find the pressure in Pa.
615 ÷ 5 = 123
123 Pa
A perpendicular force of 644 N acts over 28 m². Find the pressure in Pa.
644 ÷ 28 = 23
23 Pa
Try it yourself
A perpendicular force of 343 N acts over 7 m². Find the pressure in Pa.
A perpendicular force of 3168 N acts over 24 m². Find the pressure in Pa.

Answers and marking notes
- 49 Pa
343 ÷ 7 = 49
- 132 Pa
3168 ÷ 24 = 132
