Section 3- Pressure

Question 1

What is pressure?

Answer 1

Pressure is a measure of how much force is applied over unit area(i.e. per metres squared).

Question 2

What is the calculation for pressure?

Answer 2

P = F/A

P= Pressure in N/M2 or Pa
F= Force/N
A= Area/M2

Question 3

What are the units of pressure?

Answer 3

Newtons per metre squared, N/M2 or Pascal, Pa. This is because 1 Pa = 1N/M2.
(E.g. 20 Pa = 20N/M2)
