Wait where do you get it?

Ok... Thanks!

Ok I think I get the Isp part... You don't change "g" for the Delta-V capacity, you do for the Delta-V budget...?

Can anyone help me with the Delta-V Budget? If so... Thanks! Here it is: https://www.desmos.com/calculator/gve2r7sfl7

Yeah, That's kind of what I was going for. Like, You seeyour delta v, then you see how far that rocket can get.

Also, what about the change in gravity depending on altitude?

No, I haven't gone through calculus yet. Thank you for the help. So my graph is correct?

I will go back. I didn't see them. Thank you for pointing it out.

Ok, so I got the Delta V equation completely wrong? Because if you look here:http://www.strout.net/info/science/delta-v/ it says I got it right... And the problem with drag is the higher you go, the thinner it is. And also it depends on time in atmosphere, trajectory, velocity, and that's...

I found this for Delta V lost to drag: 1/2 * k1 * p0 * K * e^ ( -1/2 * a_net * t^2 * k2) * (a_net * t)^2 but have no idea what any of the variables mean... Here is where I got it: https://www.reddit.com/r/KerbalAcademy/comments/63nzq6/how_do_i_calculate_delta_v_losses_due_to_drag/ Does that look...

So I am making a Delta V calculator. Here it is: https://www.desmos.com/calculator/hib7psndtb Anyone know how to figure out a rocket's Delta V if it launches from in an atmosphere? Also, if I messed up on anything (in the Delta V calculator or isp calculator), please let me know so I could...
