Newton’s law
For two point masses, F = Gm₁m₂/r². Gravity is attractive and acts along the line joining the masses.
Experiment with a simplified gravitational system and observe how mass, initial velocity, and gravitational strength influence motion. The model illustrates the equations rather than reproducing the Solar System exactly.
For two point masses, F = Gm₁m₂/r². Gravity is attractive and acts along the line joining the masses.
An orbit results from gravity continually changing an object’s direction while the object retains forward velocity.
The gravitational-strength and spawn-mass values are simulation parameters and are not necessarily SI quantities.
The simulation uses simplified units, numerical integration, finite-size bodies, and a fixed central body in its preset.
Change one parameter at a time and compare trajectories. Explain changes using force, acceleration, mass, and velocity.
