Center of mass manipulatives for calculus classes
Description
Calculus Classes Often Learn How To Compute The Center Of Mass Of A Thin Plate With Varying Density. But How Can You Check That These Computations Are Actually Right? It'S Hard To Actually Get An Example Object Made Precisely Enough To Verify That The Center Of Mass Is In The Right Place... Unless You Have Access To A 3D Printer! This Thing Is A Pair Of Thin Plates With Quadratic Density Functions And Marked Centers Of Mass So That You Can Do The Calculation With Your Class And Demonstrate That The Math Is Correct By Balancing The Print On A String Or On Your Fingertip. This Material Is Based Upon Work Supported By The National Science Foundation Under [Due-12-45540](Http://Www.Nsf.Gov/Awardsearch/Showaward?Awd_Id=1245540&Historicalawards=False), 'Motivating First-Year Calculus With Robotics'.
