I have found some errors in your equations. If you are going to tell me that my code looks like chicken scratch at least have your information correct. I was just looking to see if I maybe overlooked something. I am new to programing. I have only done one program in euphoria. Maybe two in qbasic. You seem like a very lighthearted person so don't take this the wrong way. you wrote: y=vy*t - .5*g*t*t In dealing with a "projectile" that is launched horizontaly(I'll get into angles later) there are two simple equation for x and y axis. They are, x axis: x = v * t y axis: y = .5 * g * t^2 This is all you need. Where your equation above for 10m/s at 1 sec tells us that the object fell 5.1 meters the one I use (that I got out of a physics) book marks the object at 4.9 meters. I believe what you have there is the vertical *component* of an objet launched at an angle which is y = vy * t + .5 * g * t^2. If I have inserted foot in mouth please let me know. But I believe this is correct. Oh also go back and take a look at your first equation and my equation the only diffs are that I take into acount that I don't start on 0,0 coords but 50,300 coords other than that they are almost identical. You have reproduced my chicken scratch. Any one feel free to jump in please. Gee I didn't know my foot stank that bad. roachd_76
