Newton's Third Law

The Newton's Third Law Toolkit provides teachers with standards-based resources for designing lesson plans and units that pertain to Newton's law of action-reaction. The Toolkit promotes the understanding of a force as a push or pull on an object that results from its mutual and simultaneous interaction with another object. These forces come in pairs, with each force of the pair being exerted upon the two interacting objects. Much of the media and curricular resources target common student misconceptions regarding the nature of interaction force pairs. The Toolkit is supported by Lesson 4 of the Newton's Laws Chapter at The Physics Classroom Tutorial.


Each toolkit can be viewed in three different ways.

1. Newton's Third Law - HTML Version of Complete Toolkit

   The HTML version of the complete toolkit contains all the resources with full descriptions and links to their location on the web. The complete toolkit also includes learning objectives and references the pertinent standards addressed by the resources.
    

2. Newton's Third Law - PDF Version of Complete Toolkit

   The PDF version of the complete toolkit contains all the resources with full descriptions in a printer-friendly format. Learning objectives and relevant standards are also included in the PDF Version of the complete toolkit.
    

3. Newton's Third Law - Toolkit To Go

   The Toolkit To Go is a 2-page PDF document that provides an abbreviated version of the complete toolkit. It contains as much information as could fit on two pages. Toolkits to Go can be photo-copied back-to-back, hole-punched, and filed in a teacher's folder or three-ring binder for future reference.
