I made a completely new version of Kelly’s “Practice 2” from the Balanced Force Particle Model. And by “completely new” I mean that I reprinted another copy for everyone, giving more space to each of the situations on the sheet. My students were unable to include the system schema, FBD, and force vector addition diagram in the space on the first version, and I felt that the system schema was pretty important. The conceptual-level  kids have a hard time doing the FBD without the system schema. So I made it a two-sheet, four-sided document and we are working through it focusing on balanced vs. unbalanced, directions of forces, and force vector addition. So far, so good. Assessment on Thursday!
