I would think rotational resistance in such a small club from the hands would be negligible, so the torque would be negligible, meaning less club rotation from the bigger grip??? Thanks

Thanks, but I don't really now know how to do what you are saying.

It pulls realtime from the ships antenna and I'm writing javascript code to make calculations on the data. Thanks

comment How do I calculate the distance a ship will take to stop?
You guys are way too smart for me. So let's say I have 4 points in time with 4 speeds: V1,T1,V2,T2,V3,T3,V4,T4. How would I put that into the equation? Thanks

comment How do I calculate the distance a ship will take to stop?
Also I'd like to add that some ships have a block coefficient of around .8, loaded tankers, and others have a much lower one. Some ships float forever and some slow much more quickly than others. I've had ships where I was full astern trying to peel off the last 1 knot. Granted the propeller is a variable in there too. Since I am creating a system for all pilots to use, I was hoping it could be done using only velocities and times as many ships are chinese and don't have the education to determine a block coefficient. Determining exact displacement is also a problem. Thanks Again.

comment How do I calculate the distance a ship will take to stop?
Thank you for your detailed answer. The main problem is that I do not know the block coefficient of the ship. All I have is velocities and times. I was thinking that maybe figuring out the change in acceleration, jerk, would help me estimate the distance. I guess the question is will the change in acceleration be the same from 15-10kts and 5-0kts? Do you think this would work? Please remember I have limited physics knowledge. Thanks!

Well, I have limited physics knowledge. I was thinking that since the acceleration is changing, I must determine the rate at which it is changing. The problem is, I only know velocities and times for the ship. I do not know the effect the shape of the hull has on the drag or its block coefficient. I'm not sure if the jerk equation will work, but I was hoping to test it and see. Thanks
