OSP-based Programs for Advanced Physics:
Classical Orbit Demos
The classical mechanics materials use the following three OSP
programs which are found in the "Davidson package"
org.opensourcephysics.davidson:
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.
gravitation.ClassicalApp shows a planet orbiting a
massive central star in polar coordinates. The initial position (r,φ) and
velocity (vr,vφ) of the orbiting mass can be set.
nbody.OrbitApp shows two or more objects that are
gravitational attracted to each other. Any number of objects can be added with
any mass, initial position, and initial velocity.
This example shows the presentation mode for the classical orbit program
using the same parameters of the previous example.
