Skin friction, form, induced or wave drag

Use this for “Which kind of drag do a golf ball’s dimples cut, and which do long glider wings cut?”

Sort

Which drag is it mostly?
Tap a card, then tap its group.
Induced drag comes from making lift; wave drag from shocks.

Assumptions

•
Each card names the kind of drag that matters most in that case.
•
Skin friction and pressure drag add up to profile drag, the drag of a section at zero lift.
