HarmonicMotion combines two free apps to collect and analyze accelerometer data, useful for studying harmonic motion.
File data collected by 'Physics Toolbox Accelerometer' app is transformed to Excel spreadsheet 'HarmonicMotion/copy.xls' using the template spreadsheet 'HarmonicMotion/input.xls'. The template file can be edited to perform other analysis functions but note that columns 1-8 will be over-written by data.
The following are recommended apps for collection and analysis.
