  • First Online:
Smartphones as Mobile Minilabs in Physics

Abstract

In this book several previous chapters focused on mechanics experiments that can be analyzed using a mobile video motion analysis (Chaps. 3, 11, 13, 27 and 36) [1–5]. However, the use of this method is also possible in completely different areas, which is the focus of this contribution.
