PENGEMBANGAN WORKBOARD FISIKA SEDERHANA SEBAGAI KONTEKSTUALISASI TEORI MOMEN GAYA

Abstract

In learning physics, it is necessary to contextualize a physical theory by placing it in teaching aids that can prove its truth so that it can be accepted and stored by memory. This study aims to produce a set of teaching aids in the form of a work board, which is expected to be able to support the contextualization function of the moment force theory. The components that make up the workboard use simple tools that anyone can imitate. This workboard is then tested empirically to determine its accuracy by varying the force arm and load to be used. The test results show that the value of the moment of force will be greater if the value of the force arm and load is greater. This proof is obtained by the existence of a positive difference in the value of the moment of force between the force arm 0.09 m and the force arm 0.075 m, the object with a mass of 25 grams is 0.00344 Nm, an object with a mass of 105 grams is 0.0107 Nm, and a mass of 210 grams is 0.0334 Nm. In general, the developed simple workboard is able to prove the theory of the moment of force, which is proportional to the magnitude of the force, with a relative error rate of 5.45%.
