This experiment uses the sound of each bounce to retrieve its timing and calculates the values by assuming that the ball loses the same portion of energy on each bounce.

]]> Centrifugal acceleration https://phyphox.org/experiment/centrifugal-acceleration/ Fri, 06 Jan 2017 20:47:31 +0000 http://phyphox.org/?post_type=experiment&p=511 Explore the relation of angular velocity and centrifugal acceleration using the gyroscope and the accelerometer. (For example when putting your phone into a salad spinner)

]]> Free fall (acoustic detection) https://phyphox.org/experiment/free-fall-2/ Tue, 21 Nov 2017 20:30:56 +0000 http://phyphox.org/?post_type=experiment&p=1085 Using the acoustic stopwatch you can determine the duration of a free fall. (Note, that there is an alternative version using magnetic detection.)

(Note, that there is a simple an alternative version using acoustic detection.)

This experiment has been developed by Simon Goertz as a part of his thesis (in German) on smartphone experiments for linear acceleration. Another experiment from his thesis uses the same method to explore linear acceleration on an air track.

An array of magnets is used, so the linear acceleration can be explored by measuring the magnetic field.

This experiment has been developed by Simon Goertz as a part of his thesis (in German) on smartphone experiments for linear acceleration. Another experiment from his thesis uses the same method to explore linear acceleration during free fall.

As part of the work by Benjamin Götze (in German) on smartphone experiments with harmonic oscillations, he created a work sheet for schools (in German). This uses a slightly modified version of the pendulum experiment, which can be downloaded below. An alternative might be the spring experiment.

Through the pressure sensor, you can determine the changes in pressure when differen weights are placed on the bag.

This experiment was shown to us by Holger Jessen-Thiesen (Twitter), who also provided a worksheet in German, which has been translated by Solmaz Khodaeifaal (Simon Fraser University). The link at the top refers to a PDF version, but you can also use this docx file to adapt it to your needs.

This experiment is no longer available on iOS! (details)

A work sheet has been translated by Matthew Reischer (original by Mirko Zeppmeisel):
