How do I simulate a ballistic trajectory?

Open this page and use the live Gravity Well tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a ballistic trajectory from your own measurements.

Controls

The classic rubber-sheet picture of gravity: mass warps the grid, and a body orbits in the curved surface. Drag the star to move the mass and reshape the well; drag empty space to orbit the view.

Governing equation

Φ = - \frac{GM}{r} = - \frac{60 G}{r}, F = \frac{GM m}{r ^{2}}

Reading this result: At mass 60 the well is moderately curved; the body traces a near-stable ellipse because its sideways motion balances the inward pull (∝ M/r²).

About this simulation

The full Gravity Well tool models a ballistic trajectory with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
