Most of these simulations are in the old IP Student Version Player format, should be directly usable in the Macintosh Classic environment, and may or may not still be usable in the Windows environment. They were developed in a Macintosh environment and some of the fonts and screen layouts may not translate very well into the Windows environment.
The publisher has discontinued support for the Macintosh environment, a decision I do greatly regret as I have lost what was once my most favored in-class computational aid. Accordingly I no longer support this page, but maintain it as a slowly crumbling monument to better times.
At one time the following information was useful:
The simulations are available for individual download. You might want to configure your browser to launch and view them automatically with your copy of the Interactive Physics application program. To do so, you will need to edit your browser preferences. In the "file helper" area, create a new descriptor that tells your browser to link files with the extension ".IP" to the Interactive Physics application and, if desired, to open and view them with that application. Following some advice from Richard Vawter at Western Washington University these simulations have been assigned the pseudo-MIME type, "application/x-ip" which you may or may not also need to tell your browser. Professor Vawter maintains an extensive IP web site, which uses the same conventions and is well worth visiting.
IP 2.5 incorporated
errors in some of its physical formulas and specific behaviors that were
fixed and/or altered in IP 3.0 and later versions. For instance, in IP
2.x "kinetic energy" is DEFINED as mv2(!!). Thus, I have had
to manually insert a factor of 1/2 into scenarios that use the KE function.
As a result, when played with IP 3.0 (in which the KE function has been
corrected), these scenarios effectively use the formula KE = mv2/4.
Sigh. (It can be fixedif you know what you are doingby getting
into the appropriate "meters" and editing the formulae.
You can request an evaluation version of Interactive Physics from the publisher's website. If you do download the evaluation version and find that it does or does not deal with these simulations I'd like to know about it. If you are primarily a Macintosh user, you might consider adding a few words about Macintosh support in the "Comments" area of the form.)
