Abstrak— Telah dilakukan rancang bangun alat peraga fisika pada kasus gerak jatuh bebas berbasis Arduino. Alat peraga yang telah dikembangkan bertujuan untuk memvisualisasikan fenomena gerak jatuh bebas dan mengukur percepatan gravitasi bumi dan membuktikan konsep-onsep gerak jatuh bebas. Rancang bangun alat peraga menggunakan komponen elektronik seperti Arduino, sensor inframerah, sensor ultrasonik, push button, LCD, relay, dan LED sebagai komponen utama perangkat keras (hardware). Perangkat lunak (software) yang digunakan dalam mengembangkan alat peraga ini memanfaatkan compiler IDE Arduino berbasis bahasa C#. Besaran fisis yang diukur menggunakan alat peraga yang dikembangkan dalam penelitian ini adalah ketinggian benda dan waktu tempuh benda. Hasil pengujian kinerja alat peraga yang dikembangkan menunjukkan bahwa alat peraga mampu memvisualisasikan fenomena gerak jatuh bebas, mengukur percepatan gravitasi bumi dengan nilai rata-rata sebesar 10,2 m/s2, dan membuktikan konsep-konsep dalam gerak jatuh bebas.

The learning media designed is aimed at visualizing free fall phenomena, measuring earth gravitation speed, and proofing the concepts of free fall. Designing learning media using electronic components such as Arduino, infrared sensor, ultrasonic sensor, pushbutton, LCD, relay, and LED as the main components hardware devices.  Software devices which are used to improve this learning media were IDE Arduino Compiler C# language base. Physics quantity which is measured using the designed learning media in this study were the object’s height and the needed time. The test result of the designed learning media this study showed that this learning media could visualize free fall phenomena, measure the earth gravitation speed with the average score was  10,2 m/s2 , and proofing free fall concepts.

In the introductory part of the paper the author describes the method of project teaching as an alternative to the classical teaching, and presents some of the advantages of project teaching. Additionally, this method has been described by the application of this concept in teaching physics, and the author discusses the specific advantages of project teaching of this subject. At the end the author explains the example of free fall as the typical problem that can be explained by project teaching.

The State special primary acceleration measurement standard for gravimetry (GET 190-2019), its composition, principle of operation and basic metrological characteristics are presented. This standard is on the upper level of reference for free-fall acceleration measurements. Its accuracy and reliability were improved as a result of optimisation of the adjustment procedures for measurement systems and its integration within the upgraded systems, units and modern hardware components. A special attention was given to adjusting the corrections applied to measurement results with respect to procedural, physical and technical limitations. The used investigation methods made it possibled to confirm the measurement range of GET 190-2019 and to determine the contributions of main sources of errors and the total value of these errors. The measurement characteristics and GET 90-2019 were confirmed by the results obtained from measurements of the absolute value of the free fall acceleration at the gravimetrical site “Lomonosov-1” and by their collation with the data of different dates obtained from measurements by high-precision foreign and domestic gravimeters. Topicality of such measurements ensues from the requirements to handle the applied problems that need data on parameters of the Earth gravitational field, to be adequately faced. Geophysics and navigation are the main fields of application for high-precision measurements in this field.

The article examines in detail the argument of M. Friedman as expressed in his famous article "Methodology of Positive Economics". In considering the problem of interconnection of theoretical hypotheses with experimental evidence the author illustrates his thesis using the history of the Galilean law of free fall and its role in the development of theoretical physics. He also draws upon methodological ideas of the founder of experimental economics and Nobel prize winner V. Smith.
