The Uniform Circular Motion Interactive is an adjustable-size file that displays nicely on smart phones, on tablets such as the iPad, on Chromebooks, and on laptops and desktops. The size of the Interactive can be scaled to fit the device that it is displayed on. The compatibility with smart phones, iPads, other tablets, and Chromebooks make it a perfect tool for use in a 1:1 classroom.


Teaching Ideas and Suggestions:

This Interactive is intended for use near the early stages of a learning cycle on circular motion. The Interactive provides a very strong foundation for understanding circular motion concepts. The concept of an inward force and acceleration are foundational to the construction of free-body diagrams and problem-solving exercises. The use of numerical values for the various quantities provides a rich environment for investigating exactly how variations in one quantity might affect another quantity. The provided exercise that accompanies this Interactive  presents several thought-provoking questions that target common student difficulties.

There are numerous resources at The Physics Classroom website that serve as very complementary supports for the Uniform Circular Motion Interactive. These include:
  • Minds On Physics Internet Modules:
    The Minds On Physics Internet Modules include a collection of interactive questioning modules that help learners assess their understanding of physics concepts and solidify those understandings by answering questions that require higher-order thinking. Assignments CG1, CG2, CG3, CG4 and CG5 of the Circular Motion and Gravitation module provide great complements to this Interactive. They are best used in the middle to later stages of the learning cycle. Visit the Minds On Physics Internet Modules.
