Simulation of physics experiments using the octave program case study: calculation of gravity acceleration

Objective: The calculation of some physical constants requires different lab equipment and tools and time to conduct practical experiments and repeat them in accordance with the student's manual skills in dealing with different devices and tools. These experiments are financially expensive and presented with physical risks in addition to the time taken. Therefore, we can take advantage of the computer in dispensing with devices and tools and reduce the time taken to conduct experiments. There are many programs used in automated testing, most notably Matlab. But it is expensive and no ordinary person can afford it. Therefore, we will use an open-source, open-source Matlab alternative, the Octave program. In this paper we will make a comparison between the manual procedures in finding some physical constants and their mechanical counterparts using the open source program on the computer. The aim of this paper is to reduce the risk and shorten the time of physical experiments and enlightenment with the open-source Octave program and to highlight its positive aspects in how to use it in the field of physics. In this paper we will focus on the calculation of gravity acceleration as a case study and compare the results of the real procedures with the default simulation results on Octave.
