Abstract
Computational physics is introduced as one of the ways of proceeding in physics research. Six steps are outlined and exemplified in the case of two solid state analysis and preparation techniques, i.e. Rutherford Backscattering Spectrometry and Ion Implantation. Following a computational approach, a study of multiple collisions in one of their simplest forms is presented, showing how it can be treated didactically in an inquiry-based activity and discussing similarities and discrepancies with the two mentioned cases.
