The Utilization of Sensors on Smartphone to Determine the Coefficient of Kinetic Friction with the Inclined Plane in Supporting Physics Learning
This study aimed to determine the coefficient of kinetic friction with the inclined plane of some materials using sensors on smartphones that can support learning media. Determination of the kinetic friction coefficient on the inclined plane using a sensor on a smartphone by utilizing a Phyphox application connected to a PC / Laptop as remote access. The student can calculate the kinetic friction coefficient on several surfaces of objects such as wood on wood, glass on glass, and acrylic on acrylic. The acceleration value of an object when moving on an inclined plane is the basis. Also, the angle used affects the value of the kinetic friction coefficient on each material. The results of the analysis were carried out on Ms. Excel. The kinetic friction coefficient values obtained on the surface of the wooden block on wood for (0.25 ± 0.01), glass block on glass for (0.36 ± 0.03), and acrylic block on acrylic for (0.38 ± 0.01). The use of smartphones as sensors to identify physical quantities is very supportive in learning, especially experimental activities. An in-depth understanding of the theory is certainly supported by real evidence to make learning more meaningful.
