I made Gravity Simulations in Excel

Postby AlternateGravity » Thu Dec 28, 2017 6:41 pm

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 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.

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, X-Position of Planet=9.00, Y-Position of Planet=0, X-Velocity of Planet=0, and Y-Velocity of Planet=6000.

To help with replicating the inverse factorial law simulation for Row 2 Increments=0.00005, X-Position of Planet=2.70, Y-Position of Planet=0, X-Velocity of Planet=0, and Y-Velocity 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.
