</PRE>
<P>
Abstracts the notion of physical motion over time from a numeric location to another. This class can be subclassed to implement any motion equation for appropriate physics effects. <p>This class relies on the System.currentTimeMillis() method to provide transitions between coordinates. The motion can be subclassed to provide every type of motion feel from parabolic motion to spline and linear motion. The default implementation provides a simple algorithm giving the feel of acceleration and deceleration.
