I am trying to plot the velocity and acceleration of a particle as a
function of time on the same plot. I need two y axes for this purpose (each
with their units, etc.). Is such a plot possible in Mathematica ?

Check the article "Can I create a two-axis graph in Mathematica?",
Mathematica Technical Support FAQ, at
http://support.wolfram.com/mathematica/graphics/2d/twoaxisgraph.html :

"The functions TwoAxisPlot and TwoAxisListPlot, as documented in this
FAQ, enable the creation of plots with two vertical axes having
different scales. "

Also, as of today, Google returns 256 results for _two y axes_ and 254
results for _two y axis_ searched in comp.soft-sys.math.mathematica.
Some of these posts may be of interest...

JM

Ok. So, it is not a Mathematica built in. I am using Mathematica 5.0 here
and I could not find it in help. Then I realized that I needed to create my
own .m file and put it in the path.

Thanks. I wonder if it already is a part of Mathematica 5.2 or is slated to
be included in a future version. Seems too common and useful a kind of plot
for it not to be a built in.
