![]() ![]() It operates the same as this one but includes 12 different scenarios to analyze. We now have a second free-body diagram construction tool in the Physics Interactives section. Our Free-Body Diagrams skill building exercise is equipped with Task Tracker functionality. The availability of the stars on the main menu allows a teacher to quickly check-off progress on a per-student basis (if desired). For those with teachers with Task Tracker accounts (and Physics Interactives with Concept Checkers enabled), this activity can be assigned and added to students' assignment board and we will track and report student progress. After some instruction regarding the types of forces and how to recognize them and after a few examples of drawing free-body diagrams, a classroom could navigate to Free Body Diagrams Interactive and use the Interactive as an assessment/learning tool. This Interactive was intended as an in-class activity. This Interactive utilizes several situations in which an object is moving in a particular direction without any forces acting in that direction. Students who own such a misconception will often place a rightward force on their free-body diagram even when such forces do not exist. The most troublesome misconception is the insistence that an object that is moving rightward must be experiencing some type of rightward force. ![]() Identifying the forces that act upon an object is often troublesome if other misconceptions regarding force and motion exist in the mind of the learner. ![]() Considerable practice is required to master the skill. The construction of free-body diagrams is a critical skill for beginning physics students. This Interactive is intended for use near the early to middle stages of a learning cycle on Newton's second law of motion. ![]()
