Simulations
I sometimes play around with VPython/GlowScript to simulate things like planetary orbits, pendulums, spring-mass systems, spacecraft trajectories. VPython is a relatively simple way to get into it. If you've added all the force vectors correctly, you can calculate acceleration, then use Euler's Method or Runge-Kutta to calculate the velocity amd position.
(I actually thought Runge Kutta was Indian. Also science fiction author Hannu Rajaniemi, who's actually Finnish. Finns have names that can sound Japanese or Indian.)
- Pendulum by forces
- Elliptical Orbit
If your're tired of Elgoog using AI in your search results, you can use UDM14 instead.
