The measurement of the moment of inertia of a smartphone using the internal MEMS gyro to record its angular velocity as it topples over from rest in a vertical position ϑ (0) ≈ 0 to a horizontal landing has been described by Kaps and Stallmach (see Fig. 1). The analysis of this experiment is presented in terms of the conservation of energy, with the implicit assumptions that the edge of the smartphone does not slip
