Learners must decide upon the type of each force and its relative magnitude.
Each situation is described and the learner clicks/taps on-screen buttons to select forces that are directed upward, downward, rightward and leftward. The Free-Body Diagrams Interactive is a skill-building tool that allows the learner to interactively construct free-body diagrams for 12 physical situations.
