Go straight to resources ↓Pressure: the same force on less area
Average pressure is perpendicular force divided by area. With equal force, less area means more pressure. One pascal equals one newton per square metre.
| Observation | What it means |
|---|---|
| 100 N on 1 m² | 100 Pa |
| 100 N on 0.5 m² | 200 Pa |
One worked example
- F = 60 N, A = 0.2 m²The force is perpendicular.
- p = 60/0.2Divide force by loaded area.
- p = 300 PaThe force per square metre is 300 N.
Watch out: Convert area to m². Pressure is scalar; force also has direction.
Goal, prerequisites and card origin
What you will learn: Calculate average pressure p = F/A.
What you need first: Force and area.
