I have been studying videos of swimmers and find what was once called the "S" stroke has almost disappeard.
I have noticed that flyers use it. But crawl swimmers have modified it so much that it is almost gone.
Has it been replaced completely or was it an optical illusion? Did underwater film show us it did not exist.
As I said, drag your arm through the water at a constant speed, this will require force even if your arm is not accelerating.
Yes, because you are accelerating the water surrounding your arm due to the viscous shear. I still think it's F=ma whether we're talking about viscosity or not.
