The Cart and Brick Interactive is an adjustable-size file that displays nicely  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 iPads, other tablets, and Chromebooks make it a perfect tool for use in a 1:1 classroom. This Interactive does not display as nicely on all phones and we do not recommend its use on many phones.


Teaching Ideas and Suggestions:

This Interactive is intended for use near the early to middle stages of a learning cycle on momentum and collisions. It makes for a great introduction to the topic of momentum conservation and a pre-cursor to additional hands-on labwork. (It also makes a great make-up lab for those students who missed a lab on momentum conservation.) The provided ticker tape diagrams allow students to determine pre- and post-collisions velocities. If they have never performed ticker tape analysis, a short tutorial guides them through the process. The activity sheet associated with this Interactive is recommended.

Related Resources

There are numerous resources at The Physics Classroom website that serve as very complementary supports for the Cart and Brick 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 MC4, MC5, MC6, and MC7 of the Momentum and Collisions module provide great complements to this Interactive. They are best used in the middle to later stages of the learning cycle.
