- Role of friction in energy transfer.
Lecturer Procedure
| Step(s) to Follow | Expected Result |
|---|---|
| Roller should just barely make it over the first hill, and continue over the others |
| Padded roller will not make it up to the first hill. |
The default set-up for the wavy track is for use as stated above. Please specify any variations you personally may want so that the track angle can be adjusted prior to lecture.
Historical References; Taken from original work of Percy H. Carr, 1970
“In lecture point out that the waves are cut as nearly alike as possible and that the wedge adjustment has been made beforehand. Thus, if one wave is successfully passed by the roller the others should be. You can make the adjustment near enough critical that the students actually grunt to help the roller over each hump.”
“The disc on a shaft used in M-EngMom6 cannot be used here as it slides part way down the first wavy slope.”
