Pressure;
Pressure is defined as force per unit area;
“the larger the area is the lower the pressure.”
However we can describe this mathematically;
A
FP
Force ( N, Newton)
Area (m2 )Pressure (N/m2 or Pa)
Pressure is also measured in Pascal (Pa)1Pa = 1 N/m2
EXERCISE1. A force of 200N acts on an area of 4m2.
a) What pressure is produced?
b) What would the pressure be if the same force acted on half the area?
2. What force is produced if
a) A pressure of 1000Pa acts on an area of 2.0 x 104cm2?
b) A pressure of 3kPa acts on an area of 2.0 x 104cm2?
3. What pressure is exerted by a 35kg object on a surface area of 2m2?
