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. (After dragging either, the user should click "Clear Trails" to delete old colored trails from the frames.) 2.) 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. 3.) There is also a non-interactive force histogram. The force increases as distance from the segment to the point decreases. (It is an inverse distance-squared relation.

Controls
2-D Frame: Control Panel: under the 2-D drawing frame.
The play button will toggle the simulate between run and pause.
The Reset Button resets all intitial conditions and deletes old trails.
