In this article, we construct a very simple double pendulum (the concept of a pendulum should be familiar to all beginning students of classical mechanics). Since a double pendulum has two degrees of freedom, we suggest that this pendulum can be used in the classroom environment to illustrate the concept of normal modes, and we use video software…

There are several ways in the literature to determine the value of gravitational acceleration. We used an audio plug (3.5-mm jack) that can be reused from types of plugs can also be purchased and are very cheap. In this article, a computer speaker or microphone that are damaged. These value of gravitational acceleration very accurately using…

The importance of introducing computational approaches early and actively in science education is widely acknowledged among educators and scientists. Many great ideas have been put forward and implemented by advocates and organizations such as Partnership for Integration of Computation into Undergraduate Physics (https://www.compadre.org/PICUP)…

Due to the COVID-19 pandemic, in the spring of 2020 many physics programs were forced to quickly transition all of their classes and laboratories to a completely online learning environment. The need for simple and engaging remote physics laboratories became apparent. One relatively low-cost remote lab system is Macmillan's iOLab device. This…

When our school implemented AP Physics 1, I wanted to include a project that would extend over time, use more advanced data analysis, and teach students about handling experimental error. Using a donated 5-inch Newtonian telescope and an entry-level digital camera, the students gathered data from digital images of the four Galilean moons, Io,…

The possibility of negative temperatures on the Kelvin scale is intriguing and confusing simultaneously. This is because students are used to thinking of temperature as a measure of the internal energy of a system. While this concept is good for many systems, it does not work for all systems. Nuclear and electron spin systems, along with lasers…
