Thinking about actions to take: Resultant Force Sets Acceleration

There's a good chance you could improve your teaching if you were to:

Try these

• treating empirical relationships with respect
• treating the reimagining of natural motion as if it's problematic
• dealing with action at a distance respectfully
• using resultant force to predict motion

Teacher Tip: Work through the Physics Narrative to find these lines of thinking worked out and then look in the Teaching Approaches for some examples of activities.

Avoid these

• speaking as if force is the kind of thing that gets carried
• being careless about scalars and vectors
• speaking of forces trying to do things

Teacher Tip: These difficulties are distilled from: the research findings; the practice of well-connected teachers with expertise; issues intrinsic to representing the physics well.
