“…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.…”

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.

The increasing or decreasing magnetic field of a permanent magnet—attached to the bottom of the mass hanger of a spring-mass oscillator—would turn ON or OFF, respectively, the switch of a door alarm system. The sound pulses—now voltage pulses as a result of conversion by the built-in microphone of a PC—were recorded by the PC-based oscilloscope as a function of time and on the basis of these data, the period of oscillations was obtained; thus, the spring constant. We obtained (29.6 ± 0.1) N m−1 which is a good match to the accepted value of 30.0 N m−1.

Distance education has expanded significantly over the last decade, but the natural sciences have lagged in the implementation of this instructional mode. The abrupt onset of the COVID-19 pandemic left educational institutions scrambling to adapt curricula to distance modalities. With projected effects lasting through the 2020–2021 academic year, this problem will not go away soon. Analysis of the literature has elucidated the costs and benefits of, as well as obstacles to, the implementation of e-learning, with a focus on undergraduate physics education. Physics faculty report that a lack of time to learn about research-driven innovation is their primary barrier to implementing it. In response, this paper is intended to help physics lecturers and lab instructors re-think their courses now that distance learning is far more prevalent due to the pandemic. This paper serves as an all-in-one guide of recommendations for successful distanced educational practices, with an emphasis on smartphones and social media. These technologies were chosen for their utility in a virtual environment. Additionally, this paper can be used as a resource for university administrators to adapt to the changing needs associated with new teaching modalities.
