###Demo ParticleCanvasPlotter
##p1 = Particle(0, 1)
##master = Tk()
##plotter = ParticleCanvasPlotter(master, p1)

##    p1.move()
##    plotter.update()
##
##plotter.mainloop()

##Exercise: Create an extension of Particle, GravityParticle.
##in every time period, subtract 0.1 from velocity before moving.
##Start the particle at position 0 with velocity 1.5

##Exercise 2: Create two particles that are attracted to each other.
##if a particle's partner is to its right, increase its velocity
##by 0.1 in every time period.  Otherwise, decrease its velocity by 0.1
##revise particle plotter so it can plot more than one particle at
##the same time.
