Notes:
The Roller Coaster Model 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 provides the learner with a rich, interactive environment for studying both energy concepts and Newton's laws concepts for the motion of a roller coaster car. Three pre-made designs are provided - a ramp (or incline), a loop, and a series of hills. The simulation animates the motion of a coaster car along the track designs and displays energy bar charts as the car moves along the track. In addition to the pre-made track designs, learners can create designs of their own by dragging hot spots (small grey circles) to desired locations. The velocity of the car and the gravity (W) and normal (N) force values can be displayed as vector arrows; this feature can be toggled on and off. Finally, friction forces can be added or removed. Learners will quickly observe that the inclusion of frictional forces results in the loss of mechanical energy.
The environment allows a learner to study mechanical energy conservation, mechanical energy dissipation (with friction included), conversion of energy forms from potential to kinetic and vice versa, the effect of forces upon velocity, and centripetal force and tangential velocity along curved paths. Given the wide range of concepts that are addressed by this Interactive, the Roller Coaster Model could be used at just about any stage of a learning cycle in a work-energy unit or a circular motion unit. It also could be used for just about any purpose.

- 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 WE4, WE5, WE6, CG1, CG2, CG3, and CG4 of the Work and Energy and the Circular Motion and Gravitation modules 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.
