Essential Understandings for the Balanced Force Particle Model

As we work our way into the new model, here are the relevant Essential Understandings.  I post a more complete list as it becomes necessary.

BFPM

1)      System Schema

I can use a system schema to show an appropriate choice of system, identify objects that interact with it, and determine the appropriate number of interactions.

2)      Force Diagram - Labeling

I can draw/interpret force diagrams, labeled with force type, feeler, dealer, and equality marks, with the appropriate number of forces, and precisely showing the direction and relative magnitude of each force.

3)      Weight and Mass

I can distinguish the difference between weight and mass.  I know the value and units for the Earth’s gravitational field strength near its surface.  I can use it to calculate mass or weight.
