Charles: it could be tweaked but it would require two more input variables. Roy 14/11/07 : an excellent tool but for one thing! would it be possible to produce a version with imperial input values for those of us who still live in the stone age...;-) Apostolos 21/05/08 : The calculator is back in order! It mesures it very i have some the calculation inculdes the air friction,arrow weight ext?Or its just enought to know the sight difrence between two distance?bestel 17/07/07 : Hi Apostolos and congratulations, great job !I'd like to translate it in french in order to use it on my club website (it would display your translated page inside a frame).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?
It's very helpfull and so helped me to verifie my estimation of the speed of my arrows. But then thinking about the speed of most compounds (300 fps) this would make sense.
Perriswood Dick 30/03/07 : I can see how the algorithm accounts for different arrow size/weight but where is limb/r1ser length and draw weight taken into account RLH Apostolos 01/04/07 : In fact, we don't care about the draw weight but only for the angle difference between the two distances. I was also thinking of doing another version that could calculate your arrow speed loss per meter given all of your sightmarks. Could you please help me figure out how to measure speed of an arrow (point blank) just with draw weight (45 lbs) and arrow weight (385 gr)?
I would like to find out my arrow's speed so I could figure out its foot-pounds of energy. ben 17/06/07 : this formula is all well and good but what arrow weight is it going off?
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...
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.
