Abstract

Experiments have been carried out by utilizing technology in free fall motion material to support learning physics through practicum that can be done by students anywhere. This experiment is relatively simple, but quite successful in determining the gravitational acceleration. Apart from being able to be done anywhere, this experiment is also economical and affordable. That is, it does not require complicated or difficult to obtain equipment. By using HVS paper, a pen, and the PhyPhox application on a smartphone that has an acoustic stopwatch sensor, as well as easy experimental procedures can help teachers in physics teaching. Based on the results of data analysis, the value of the acceleration due to gravity is ? = 9.679 m/s2 with an error percentage of 1,332 %. These results indicate that this experiment is quite successful and feasible for use by the teacher for practicum material free fall motion about determining the gravitational acceleration to students.

Key Words: physics teaching, gravitational acceleration, smartphone, PhyPhox, acoustic stopwatch
