“…While all device drivers and software libraries were free, it was necessary to write software to acquire and record the LPS data. Our in-house software application is available for public, non-commercial use [27]. Finally, this product implements a finite number of independent communication channels, with a maximum of 12 independent systems simultaneously operated in the same space.…”

“…A balloon was also tagged and dropped; see figure 1(b). Lastly, an air-powered projectile made by Arbor Scientific was fitted with a 3D-printed fuselage [27] that could accept the tag. The projectile has not only a smaller cross-section-to-mass ratio ratio than any of the balls, but a spherically blunted conic nose cone, as well, making it likely to experience the least drag.…”

A new series of introductory physics experiments for teaching the kinematics and dynamics of falling bodies is presented. These learning activities are enabled by newly available position-tracking technology that allows for the direct acquisition of coordinate data from moving objects. Students are led through an iterative inquiry process that explores both free fall and drag-enhanced physical models, for different velocity regimes, emphasizing a comparative modeling approach to science. Learners discover how the experimental design, including the properties of the dropped objects, the dropping distance, and the uncertainty of the measuring device, impacts the ability to explore the validity of physical models with or without drag.
