Physics FX is a software tool that emulates physical phenomena on teacher and student computer screens. There are eleven experimental modules. The site license is permanent with no annual support fees. Purchasing schools may install the software on as many school machines as they wish or on a network within the school. Students may be given photocopies of the activity pages. For student reports, tests, and exams, a built-in copy feature captures any screen image/diagram for pasting into a word processor.
