1
Q

A
The ability of a fluid to exert an upward force on an object
2
Q

3
Q
pressure formula triangle
A
paf
4
Q
Pascals Principle
A
Pressure applied to a fluid is transmitted unchanged throughout the fluid.
ex. Squeezing toothpaste
formula: f1/a1=f2/a2
5
Q
What type of areas do fluids move faster through?
A
Small, narrow areas.
6
Q
Bernoulli’s Principle
A
As the velocity of the fluid increases, the pressure decreases.
7
Q
Boyle’s law
A
As the volume of the gas decreases, the pressure increases.
formula: p1v1=p2v2
8
Q
Charle’s law
A
As the temperature increases, the volume increases.
v1/t1=v2/t2
