摘要:
A low -cost Global Positioning System (GPS) is used to determine the magnitude of the resultant of two displacement vectors. A physics class takes a field trip to the school’s football field. Then using the GPS, the students mark the corners of the field. The class then compare the calculated measurement of the field’s diagonal to that obtained from the GPS. Information and references are provided concerning the capabilities and limitations of the GPS.
