velocity and force example

Posted 2024, Apr 09 19:56

if 4 knots to 16 knots is a change of force by 16 times how does 4 knots to 32 knots equate to a force change of 64 times? per the text, the increase is 4 times but 4 times what amount? the difference between? that can't be it because neither example would be correct. sorry, Im mathmatically challenged but I can't see how these numbers are working. Thanks!

I think I found one. On the Wind Meter (?)

I read somewhere very recently the true wind angle is “always 100% guaranteed” to be more toward 180deg than the apparent wind angle. Yes? ML
