About

The Free-Body Diagrams Interactive is a skill-building tool that presents users with 12 physical situations for which they must construct free-body diagrams. On-screen buttons are used to select up-down-right-left force types. Force arrows can be clicked/tapped to toggle the magnitude of the force. Feedback is immediate; opportunities to correct answers are endless. Built-in score-keeping makes this Interactive a perfect candidate for a classroom activity.
