Exponentially damped oscillatory motion is often encountered early in a physics student's education. The closed form solution in the case of linear-in-velocity drag makes this an attractive first model, but realistic systems typically include constant- and/or quadratic-in-velocity drag. The equations of motion for non-linear drag can be solved numerically so that data can be fit using more accurate models. A data set is presented and analyzed which students can use to explore topics such as differing models of friction, numerical modeling techniques, and evaluating and quantifying the agreement between a model and data. Code and data are provided for physics instructors' use.

Simple epidemiological models are introduced using finite difference methods in Excel. The SIR model explains the initial exponential growth of COVID-19, the effects of social distancing in the US during early April 2020 and successfully predicts the continued spread of the virus during late April and May 2020. The SIR model is the origin of the basic reproduction number R0 and herd immunity. It also predicts what will happen if social distancing is lifted prematurely. A wide range of student research projects are possible for modeling and making predictions based on real data for US states and other countries.

Understanding COVID-19 by modeling it

Radiology practitioners are examined on the underlying radiological physics principles of Photoelectric Absorption and Compton Scatter. Students must understand how these interactions in the patient vary as the x-ray tube acquisition parameters are adjusted. This variation changes the relative tissue contrasts in the radiograph and the detrimental radiation dose to the patient. An interactive Mathematica (1) simulation has been developed which simultaneously shows relative interaction probabilities, patient dose & penetration, and an anthropomorphic chest image. By adjusting the parameters the student can determine an optimal acquisition which minimises patient dose whilst generating sufficient contrast for lesion detection on the radiograph. The simulation instructions lead the student through a series of acquisitions which enable MCQ & SAQ assessments, which have demonstrated enhanced and accelerated comprehension. 1.
