I made Gravity Simulations in Excel
I figured out how to simulate orbital motion in Excel using time step increments, formulas, and graphs.
I started by simulating orbital motion using the inverse square law
I also simulated an orbit using the Linear Law

Gravitons would be my favorite particle as their existence could prove extra dimensions.

I also simulated orbital motion using the factorial law

Finally I simulated orbital motion using the inverse factorial law

Re: I made Gravity Simulations in Excel
I did some more of the simulation using the inverse cube law
Also these are the excel files I used. I had to shrink them down to the minimum amount of information needed to replicate the data needed for the graphs as when I had them filled to row 300000 they were to big to attach. You can simulate orbits, using these excel files, by filling from Row three to Row 300000.

Re: I made Gravity Simulations in Excel
Unfortunately I could not attach the factorial law and inverse factorial law simulation.

To help with replicating the factorial law simulation for Row 2 Increments=0.00000025, XPosition of Planet=9.00, YPosition of Planet=0, XVelocity of Planet=0, and YVelocity of Planet=6000.
To help with replicating the inverse factorial law simulation for Row 2 Increments=0.00005, XPosition of Planet=2.70, YPosition of Planet=0, XVelocity of Planet=0, and YVelocity of Planet=6.
To help with replicating both simulations; In Row 2 the mass of the planet and the mass of the star is the same as in the other simulations, the position and velocity of the star are the reverse of the position and velocity of the planet divided by 10000, and the time passed is 0. In Row 3 the formulas for the positions, velocities, increments, and time passed, and masses use the same formulas as in the other simulations. Also the formula for x! in excel when x may not be an integer and when x is positive is x*EXP(GAMMALN(x)). Also I used ten graphs with the first graph going from B2 to C30000, the second graph going from B2:C60000, the third graph going from B2:C90000, and so on to the tenth graph.

Re: I made Gravity Simulations in Excel
I did some more simulations using excel starting with a simulation of a hyperbolic "orbit" using the inverse square law
I also simulated orbital motion using the Sin Law
