“…Using the overall oscillating mass, that is m=191,3 g, and the equation of, , eventually leads to the spring constant of, k2=33,67N/m. The results obtained from two distinct approaches are in a very good agreement with each other and overall method is well-matched with the approach offered by Pili (2018).…”

“…In the application, one can measure central concepts such as pressure, sound intensity, light intensity, magnetic field and position and one can also monitor the relating graphs of the data selected within the application. The application can carry out complicated experiments and retrieve the data in a more practical way without having any additional measurement tools (Monteiro & Martí, 2016;Pili, 2018;Pili & Violanda, 2019). In the present work, the posometer sensor of the physics toolbox sensor suite is employed and basically the illumination intensity coming from the light source is plotted as a function of time with the help of the posometer sensor.…”

“…Measuring spring constants with a vertical spring mass oscillator is a standard high school laboratory activity. Traditionally, the oscillation period of the spring system is measured with a fault-prone stopwatch due to the adverse effect of the reaction time of the experimenter (Pili, 2018). The use of smartphones, in elementary experimental physics, has been a popular activity and existed for a number of years (Çoban & Erol, 2019;Countryman, 2014;Dilek & Erol, 2018;Erol & Çolak, 2018).…”

This study aims to develop a teaching proposal to measure spring constants of various spring-mass systems by means of the smartphones. Specifically, a single spring-mass system, a serial connected and a parallel connected spring systems are experi-mentally resolved, by using the ambient light sensor of the smartphones. The measurements are achieved by simply recording the light intensity, detected by the oscillating smartphone, as a function of time for the simple harmonic motion. Using the light intensity-time graphs, the average periods and eventually the spring constants are estimated and the outcomes are compared with the theoretical results. The overall outcomes of the work indicate some 3,3 % relative error for the serial connected springs and 10,8 % relative error for the parallel connected springs. The approach is important in the sense that the apparatus directly plots instantaneous momentum-time graphs and it creates an enjoyable and beneficial teaching atmosphere.

“…Numerous studies have explored the utilization of smartphone-based sensors as practical tools in various contexts. For instance, researchers have employed a light sensor within the PTSS to ascertain the spring constant [12], measured sound intensity [13], determined the elastic constant of a helicoidal spring [14], and even assessed the moment of inertia of rigid bodies using a smartphone magnetometer [10]. Additionally, scholars have incorporated smartphone-based sensors into the realm of SHM.…”

One of the common challenges encountered when conducting physics experiments is ensuring measurement accuracy. Conversely, the emergence of smartphone-based sensor applications presents an opportunity to address these issues. Thus, this research aimed to assess the effectiveness of Physics Toolbox Sensor Suite (PTSS), a smartphone-based sensor, in enhancing students’ conceptual mastery of simple harmonic motion. The study employed a non-equivalent control group design, with a valid and reliable multiple-choice test as the research instrument. The sample comprised 70 2nd grade students from a public senior high school in Indonesia, with 35 students for each experimental and control group. The research was conducted during the Even Semester of the 2022/2023 Academic Year at a public high school in Lampung Province. Both groups were instructed using the same pedagogical approach-discovery learning. However, the experimental group conducted experiments aided by PTSS, while the control group did not. N-gain analysis revealed a greater increase in conceptual mastery within the experimental class compared to the control class. The average n-gain for the experimental group was 0.74, whereas for the control group, it was only 0.64. Furthermore, the Mann-Whitney test indicated an Asymp. Sig. (2-tailed) value of 0.004, smaller than 0.05, suggesting that smartphone-based sensors like PTSS could facilitate simple harmonic motion experiments and enhance students’ conceptual mastery.

“…Several experimental studies related to oscillation and oblique biding have been carried out using light sensors on smartphones. For example, the determination of spring coaster with a good level of accuracy [5] as well as determining the acceleration and speed of objects in the inclined plane with a good level of accuracy [6]. Based on these studies, researchers tried to develop it into new research to determine the oscillation period of spring systems and block on the inclined plane using a light sensor on a smartphone.…”

The topic of oscillation in spring and block systems in the inclined plane is fairly complex and rarely to be discussed in the oscillation research topic. Not only theoretical calculations, physical quantities in this topic can also be calculated through experiments. This research determines one of the physical quantities present in this system, namely the oscillation period experimentally with the help of a light sensor on a smartphone. Experiments were carried out with variations in angular position on the inclined plane with spring-mass block launched from the top of the plane. The spring used has a constant (2.68313 ± 0.002152) N/m while the block has a mass of 0.0892 Kg. Through weighted linear regression analysis, this study shows a linear relationship between the angular position of the inclined plane and the oscillation period with a linear equation y =-0.005x + 1.3661 and R 2 = 0.98358. The greater the angle of the incline, the smaller the value of the oscillation period. These results can provide further development of the use of light sensors on smartphones for physics experiments, especially in spring systems and block on inclined planes.
