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 hammer throw 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.
