Measurement of Coriolis Acceleration with a Smartphone

Abstract

Undergraduate physics laboratories seldom have experiments that measure the Coriolis acceleration. This has traditionally been the case owing to the inherent complexities of making such measurements. Articles on the experimental determination of the Coriolis acceleration are few and far between in the physics literature. However, because modern smartphones come with a raft of built-in sensors, we have a unique opportunity to experimentally determine the Coriolis acceleration conveniently in a pedagogically enlightening environment at modest cost by using student-owned smartphones. Here we employ the gyroscope and accelerometer in a smartphone to verify the dependence of Coriolis acceleration on the angular velocity of a rotatingtrack and the speed of the sliding smartphone.

High frequency signal acquisition using a smartphone in an undergraduate teaching laboratory: Applications in ultrasonic resonance spectra

“…Over the past ten years, much has been written about the use of smartphones for acoustic measurements [5][6][7][8][9][10][11][12][13][14] and scientific measurements in general. [15][16][17][18][19][20] Due to the ease of interfacing with the internal microphone and the limited bandwidth of the smartphone analog-to-digital converter (ADC), the studies mentioned above have focused almost exclusively on the use of the internal microphone to make measurements of sound in air and in the audible frequency range. In Refs.…”

Studying cooling curves with a smartphone

“…T his paper describes a simple procedure for the study of the cooling of a spherical body using a standard thermometer and a smartphone. Experiments making use of smartphone sensors have been described before, contributing to an improved teaching of classical mechanics, [1][2][3][4][5][6][7][8][9][10][11] but rarely expand to thermodynamics. [12][13][14] In this experiment, instead of using a smartphone camera to slow down a fast movement, we are using the device to speed up a slow process.…”
