Smart accelerometer: measuring circular motion, centripetal force and the graph of acceleration with smartphones
The teaching unit ‘A Smart Accelerometer’ shows the students how the effects of the speedup can be measured by the smartphone. With two practical experiments on a record player and a rotating fairground ride the students do research on the motion in low an high scales. The sensor of the Smartphone shows the effect of the acceleration along the three axes whereat the position of the Smartphone is determining for the result. Using an app the relation between the graph of acceleration and the radius as well as the equation of the linear fit can be found out.
For this teaching unit the students should be at an age between 15 and 18 years, for certain knowledge in physics, maths and informatics are presumed.
