An Easy-to-Use Magnetic Dynamometer for Teaching Newton’s Third Law

The study of Newtonian mechanics gives students the first chance to question their commonsense assumptions and replace them with a more comprehensive worldview. is cornerstone contemporary science. Furthermore, despite its essential significance, multiple studies demonstrate how challenging it properly comprehend key elements Newton’s equations. Any initiatives increase teaching options are therefore encouraged. In order help instructors in particular applications third rule action-reaction, we provide an experimental instrument. Our method consists two flexible plastic strip dynamometers that have miniature neodymium magnetic disks connected them. amount force being transferred using field shown by strip’s radial distance. This very affordable arrangement simple assemble, efficient, appropriate for many programs call trial kits.
