Newton's Third Law
Forces and Motion
Thinking about actions to take: Force Pairs Replace Interactions
Teaching Guidance
for 14-16
There's a good chance you could improve your teaching if you were to:
Try these
- using interaction diagrams
- connecting the study of Newton's third law to earlier understanding of Newton's second law
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
- presenting the law as obvious
- presenting the Newton three pair of forces as both acting on one object
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.
