>1. q1*q3*k/(r^2)= F1_3(this is the electric force between 1 and 3)

>2. q2*q3*k/r^2)= F1_2(force between particle 1 and 2)

>3. from there i can find the net force between the two charges with f1_3+f1_2=fnet

>4. with the net force i would then find the acceleration using a=fnet/m (with m being the mass. (now everything above i was okay with doing but now heres where i get confused)

>5. take the acceleration just found and find velocity. v=-(at) being time intervals (i got that equation aver deriving it from the equation in step 6 and the initial equation was x(.05)=at+v

>6. take that velocity and previous acceleration and find new position: x=1/2at^2+v*t+x

>7. the value for x becomes the new position for particle 3 and now i go back to to the top in order to calculate electric force then acceleration etc rinse and repeat.

Is what I'm trying to do not possible? I just dont know how i would take the new position i get and re-implement it back into the other methods to spit out another value at the end what i have in the code below is just one rotation of a equations that i would like to use numerous amount of time. The reason for me doing this is because for every position and time I want to save those values and plot them later. Someone recomended to me an using an array but im do not know how to use them nor do I understand how that may help

`q3`needs to take the value of

`wow`for the next round of calculations, you would simply assign the value of wow to q3 (line 8 below)

Your names seem very cryptic to me. Why use names like "wow" and "q3"? Unless these are names like "delta" and "lambda" that have common, well-known meanings, they don't make your code very readable.

Well, you could make it easier for people to help you if you used some punctuation, proper capitalization, and apostrophes. Most folks prefer to read posts that don't make them do a lot of copyediting on the fly.

A while-loop is one way you can repeat a set of instructions. It terminates when its loop condition evaluates to false. You can read more about while-loops here: https://docs.oracle.com/javase/tutorial/java/nutsandbolts/while.html

Like I said, the calculations and the progression is not very evident to me from your code. Maybe it will help if you give examples of a few iterations of calculations so that we can see the relationships and patterns of change between one iteration and the next.
