How do you Calculate Pressure
Force(N)/Area(m2)
Force(kg)/Area(mi2)
Area(m2)/Force(N)
If an object's surface area is smaller does it create more or less pressure?
More
Less
The same
What is pressure?
The amount of force exerted on a surface
The surface area of an object
The weight of an object
A person weighs 700N and their feet have a surface area of 0.1m2. How much pressure is exerted?
7000N/m2
70N/cm2
100N/m2
If you're walking in snow why would you wear boots instead of high heels?
Because boots have a higher surface area making the pressure less and stopping you from sinking.
Because it's more comfortable
No, high heels are better
What does N/m2 mean?
Newtons per squared metre
Kilograms per squared mile
Squared metres per newton
How do you turn Ncm2 to Nm2?
Divide by 100
Divide by 10
Times by 100
Why won't you sink in mud if you wear boots?
Because the surface area is larger creating less pressure.
Has air in it to keep you floating.
Because the mud won't want you.
Why do you wear studs on grass?
Because the studs create more pressure allowing it to grip into the grass.
Stylish
Creates friction
State the direction at which pressure acts?
420o
180o
90o
