A
true
2
Q
2 different fluid states
A
laminar - fluid flows
turbulent flow -
3
Q
form drag?
A
drag due to shape
4
Q
surface drag?
A
friction drag
5
Q
what is the most important term in the drag equation?
A
velocity
6
Q
bernoulli’s principle?
A
increase in the speed of a fluid results in the reduction in the pressure of a fluid
7
Q
what acts perpendicular to drag?
A
lift
8
Q
magnus affect
A
spinning we get that break in airflow symmetry we get a pressure differential therefore we have a force moving us to the side
9
Q
Air resistance?
A
Object moves through the air it creates disturbance
10
Q
How to stop drag?
A
Clothing
Equipment
Technique
