Slash-Dot System Model
written by Johnny Pav
The Slash-Dot Model simulates a massive line segment and massive point rotating about one another due to gravity in a 2-dimensional plane. The simulation tracks the obits of the line segment (or "slash") and the point (or "dot") with colored trails. It also shows vectors of slash/dot velocity and acceleration and has a histogram depicting force. The white slash and dot are draggable. The orange velocity vectors are draggable: Simply click on the triangle of the arrow and drag around the plane. The longer the arrow gets, the greater the velocity of the slash or dot.

The Slash-Dot System Model was created using the Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_comp_phys_slash_dot.jar file will run the program if Java is installed.

Please note that this resource requires at least version 1.5 of Java (JRE).
