OSP-based Programs for Advanced Physics:
Classical Orbit Programs

 

gravitation.PlanetApp shows a planet orbiting a massive central star in Cartesian coordinates. The initial position (x,y) and velocity (vx,vy) of the orbiting mass can be set.
You can change the following parameters in the OSP Control window:

x0: sets the initial position in the x direction.

y0: sets the initial position in the y direction.

vx0: sets the initial velocity in the x direction.

vy0: sets the initial velocity in the y direction.

dt: sets the time step.
