Class Particle

java.lang.Object
  org.opensourcephysics.sip.ch02.Particle

Direct Known Subclasses:

FallingParticle, SHOParticle

public abstract class Particle
extends java.lang.Object

Particle models a one-dimensional trajectory that can be computed analytically and numerically. This class is abstract because the dynamics of the particle's motion is not yet known.

Constructor Summary

Particle()
Constructs a Particle.

Method Summary

protected abstract double	analyticPosition() Computes the position at the current time using the analytic solution.
protected abstract double	analyticVelocity() Computes the velocity at the current time using the analytic solution.
protected abstract void	step() Steps (advances) the dynamical variables using a numeric method.
