The question
Question: find the pressure when the force is 600 N and the area is 2 m².
Force 600 N, area 2 m². Find the pressure.
1 Write the rule
The rule: pressure is the force divided by the area.
pressure = forcearea
Pressure tells us how much force pushes on 1 m².
So its unit is N per m².
pressure = the force on 1 m²
unit: N ÷ m² → N/m²
2 Put the numbers in
The force is 600.
The area is 2.
p = 6002
3 Work it out
Careful!
The force goes on the top.
The unit, N/m², shows it: N on the top.
Careful: not 2600 ✗
600 divided by 2 is 300.
pressure = 300 N/m²
So the pressure is 300 N/m².
4 Check
Let's check.
300 in each m², for 2 m²: 300 times 2 is 600.
That is the force.
So the answer is right!
300 N in each m²: 300 × 2 = 600 N
Let's look back.
First: write the rule.
Then: put the numbers in.
Then: work it out.
Last: check.
Answer
pressure = 300 N/m²
