Manipulate the Euler angles in this Applet and observe the rotation in Euclidean coordinates. There is a description of the Euler angles here .
This demonstration is useful for points in a three dimensional space. It is found in many visualizing applications.
This applet displays the motion of a particle for general spherical potential. One can define the potential and observe the resulting trajectory as well as the effective potential.
To execute you need Mathematica or the free Wolfram CDF Player.
This applet shows the motion of two bodies with attractive gravity force. Both have the same initial velocities. Varying the masses you can see movement of the center of mass. You can show the motion in absolute and relative coordinates.
To execute you need Mathematica or the free Wolfram CDF Player.
Hinweis: Zum Ausführen der Demonstrationen wird der kostenlose Wolfram CDF Player (Win,Mac,Linux) oder Wolfram Mathematica (Version 6 oder höher) benötigt.
Der Quellcode (*.nb Datei) ist ebenfalls zum Download verfügbar und lässt sich mit Wolfram Mathematica ausführen.
