Use your phone’s barometer to measure the vertical velocity of an elevator – or a quadcopter…
This is the second of two videos on oscillations with phyphox. This one is about building pendulums and how we collected the data from our students to confirm the simple pendulum model.
(Sorry for the distracting ring light – just threw in all the lighting…)
In this short video we demonstrate a simple emthod to measure the speed of sound with just two phones and a tape measure
The experiment, which explores centrifugal acceleration in a salad spinner, has only been added in the update before the last one. But it has become one of our favorites as few others are that simple and yet give such beautiful results.
The sonar might be one of the most fascinating experiments, but also one of the most confusing ones if you do not know how to do it properly. This video explains, how to turn your phone into a sonar.
The magnetic ruler is more a tool than an experiment on its own. It allows you to determine distances and speeds by marking distances with simple magnets.
In this experiment, you can track the velocity of a roll using the gyroscope of your smartphone.
