I understood everthinng up until the complex calculations :) thanks for the clear, informative write up and graphs! I shall drop them an email with a link here to see if they can shed some light onto how they came to those results. Would it be possible to do those same calculations but...

Sorry my fault I wasn't clear. The lighter object would have a starting velocity of 350 feet per second and the heavier 313 FPS. Trying to use the same power output (1.14joules?). I don't know the person who created those particular graphs and in currently trying to get hold of them, if I do...

Thanks for that much appreciated. Just noticed the lower initial velocity. So that will have the same effect on both weights, higher speed causing more drag increasing the deceleration. Is it possible/easy to work those numbers back to have a starting velocity of 350fps? Or should I assume the...

Unfortunately a practical test wouldn't be accurate as they have a rubber part to create backspin on the ball bearings giving lift whilst in flight. But I've taken this out of the equation to save complication (it's unpredictable ). You suggest using the 'time the objects exit the muzzle till...

If it's too time consuming to work it all out would it be possible to apply the effect of gravity onto the calculations made in the link (above post)? Q: If 2 objects are dropped from the same height with the same aerodynamic properties they hit the ground at the same time right? (lets say 1...

Many thanks and it's making sense so far which is good :) Don't know if it's of any help but this discussion has been going on sometime and there is some info/calculations at http://www.arniesairsoft.co.uk/?filnavn=/articles/fps_dist_time/fps_dist_time.htm ignore the bumf at the start and...

I've been having a discussion with some friends at a local Airsoft club for some time now and we are unable to agree on the flight distance's of identical objects that have different masses. I'll try to explain... If a 6mm spherical object, weighing 0.2g, was fired on a horizontal path with a...
