Notes:
The Free-Body Diagrams ... The Sequel Interactive is an adjustable-size file that displays nicely on smart phones, on tablets such as the iPad, on Chromebooks, and on laptops and desktops. The size of the Interactive can be scaled to fit the device that it is displayed on. The compatibility with smart phones, iPads, other tablets, and Chromebooks make it a perfect tool for use in a 1:1 classroom.
Teaching Ideas and Suggestions:
This Interactive is intended for use near the early to middle stages of a learning cycle on Newton's second law of motion. It is the second free-body diagram construction tool in our Physics Interactives section and was inspired by the original
Free-Body Diagrams Interactive. The construction of free-body diagrams is a critical skill for beginning physics students. Considerable practice is required to master the skill. 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. The most troublesome misconception is the insistence that an object that is moving rightward must be experiencing some type of rightward force. Students who own such a misconception will often place a rightward force on their free-body diagram even when such forces do not exist. This Interactive utilizes several situations in which an object is moving in a particular direction without any forces acting in that direction.
This Interactive was intended as an in-class activity. 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 ... The Sequel Interactive and use the Interactive as an assessment/learning tool. Since we now have two of these FBD construction tools, it might be best to attempt the original
Free-Body Diagrams Interactive followed by this one ("The Sequel"). 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 customized, assigned, and added to students' assignment board and we will track and report student progress.
Our Free-Body Diagrams skill building exercise is equipped with Task Tracker functionality.

- Minds On Physics Internet Modules:
The Minds On Physics Internet Modules include a collection of interactive questioning modules that help learners assess their understanding of physics concepts and solidify those understandings by answering questions that require higher-order thinking. Assignments NL2, NL3, NL4, and NL5 of the Newton's Laws module provide great complements to this Interactive. They are best used in the middle to later stages of the learning cycle.
