Density and Pressure Flashcards
1
Q
How to calculate Pressure
A
Pressure = Force / Area
2
Q
what is pressure measured in?
A
N/m² or N/cm²
3
Q
what is a Pascal?
A
1Pa=1N/m²
4
Q
what causes a higher pressure with the same force
A
a small area = high pressure
a large area = low pressure
5
Q
How to calculate Density
A
Density (g/cm³ or kg/m³) = Mass (kg or g) / Volume (cm³ or m³)
6
Q
how to calculate Mass
A
Mass = Weight * Gravity
Gravity of Earth is 10N
