Universal Gravitation

The Universal Gravitation Toolkit provides teachers with standards-based resources for designing lesson plans and units that pertain to introductory concepts associated with Newton's Law of Universal Gravitation. Such concepts include the Apple and the Moon argument, the inverse square relationship between the gravity force and separation distance, the Universal Gravitation equation and associated proportionality constant, and the gravitational field strength. Misconceptions are addressed and a good deal of history is introduced. The Toolkit is supported by Lesson 3 of the Circular Motion and Satellite Motion chapter at The Physics Classroom Tutorial.

Each toolkit can be viewed in three different ways.

  1. Universal Gravitation - 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. Universal Gravitation - 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. Universal Gravitation - 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.
