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!

It is the square of the velocity

thank you. so to ensure I understand this, if velocity was increased to 64 knots (YIKES) then the force would be 256 times (64 x 4).. the x4 because the velocity doubled from 32 to 64. Is this correct?

True. It’s why hurricanes are so destructive.
