I am doing this for my science fair project, and I am soooo confused!
I am only trying to find an easy way to find out how fast the arrow went...
Arrows of composed of different materials, weights, lengths and the bow being used all play a factor.
Most (if not all) archery clubs have a radar device in which you place it near the target and shoot the arrow through it (from about 10 feet away / the arrow will have maximum velocity shortly after it's release). Ludek 13/08/09 : Hello, it is also good for bare bow, i tried it.
I am very happy to live with this minor issue, but if you ever found yourself with nothing to do sometime ........!!! Best wishes, David Morrish Harry Marx 03/09/08 : I did the same thing, but derived formula myself. Normally the arrow is shot at 42 to 47 degrees with specialist bows?
I have studied balistics but have no luck with the maths. helped me with science fair Apostolis 13/01/09 : Thank you all for your comments. I am shooting field ranges where uphill/downhill calculations depend on arrow speed. Sam S44 22/03/09 : Can you give us Yards and inches?
If I find some time, I will update the calculator with your suggestions. Joan Smith 05/06/09 : I was asked how fast an arrow travels so I Googled to find out.
I found this and thought the very thing I'l just print this out for future questions! Robin Of Locksley 19/06/09 : This calculator is quite vague (even for English standards).
plz some one help me out this project is due next tuesday and i have nothing.I am doing this for my science fair project, and I am soooo confused! what in the world is 'sight mark setting' and 'eye to sight pin'??????I am only trying to find an easy way to find out how fast the arrow went... I'm not in any club and I can shot when I can- which is not very much.All the results are fairly accurate, congrats on a job well done.
paul f 08/09/10 : i have access to a speed gun would that work too kayla 10/09/10 : that is cool Li 01/10/10 : This calculator works pretty well.
I'm not a ballistic engineer, but very curious about how you find the formula. Just to test the calculator I entered a 10cm difference between to distances - then you can see how the decceleration, gravitational and other forces start to show a non-linear relationship. Mark 25/09/09 : Robin or Locksley : The things you mention are constants for the two shots from you bow setup and your arrows. Decceleration, gravitational forces and other forces are taken into account by the formular - see my earlier comment.
