Pressure
Flashcards do conjunto (9)
- 1Define pressure.The measurement of force exerted on a surface
- 2Explain the relation b/w area and pressure.-The smaller the area of a surface (measured in m2), the higher the pressure if force (measured in N) applied remains constant
-The larger the area of the surface, the lower the pressure if force remains constant - 3What is the formula for pressure?P=F/A
- 4Area is measured in?square meters (m2)
- 5Force is measured in?Newtons (N)
- 6What is the SI unit for pressure?Pascal (Pa)
- 7What does 1Pa equal?1Pa=1N/m2
- 8What is the relationship b/w pressure and area?-Pressure is inversely proportional to the surface area upon which force is applied
-It means that as area decreases, pressure increases (when force remains constant) - 9What is the relationship b/w pressure and force?-The change in pressure is directly proportional to the force applied
-It means that if the area remains fixed and force increases, then pressure also increases
