## Free-Body Diagrams for Inclined Planes

The Free-Body Diagrams for Inclined Planes Concept Builder includes a bank of 32 questions organized into 8 Question Groups and spread aross three difficulty levels. Each question provides a description of an object moving up or down an inclined plane. Learners must construct the free-body diagram for the situation. The process involves selecting a force in the appropriate direction and giving it a force label. The three difficulty levels are differentiated as follows:

• Apprentice Difficulty Level Question Groups 1-4: Includes our most basic situations of a box moving up or down and inclined plane with or without friction.
• Master DifficultyLevel Question Groups 5-8: Includes our most complex situations in which a box is pulled up an inclined plane by a rope or a person with or without friction.
• Wizard Difficulty Level Question Groups 1-8: Includes all questions from the Apprentice and Master Difficulty Levels.
