General Physics 1.8 Pressure Flashcards
1
Q
Give the equation for pressure.
A
pressure = force / area
P = FIA
2
Q
What are the units for pressure?
A
Pascals, Pa
3
Q
Pressure in a fluid ________ with depth. Why?
A
Increases, because it is caused by the gravitational force of the fluid above that point.
4
Q
Give the equation for pressure at different depths of a fluid
A
pressure (Pa) = depth (m) x density (kg/m3) x
gravitational field strength (N/kg)
p = hpg
5
Q
What does an object in a fluid experience as a result of pressure?
A
Forces at right angles to all of its surfaces.
