The idea is to use an inquiry method to find the position of the accelerometer in the smartphone without open it (of course !). This work is for a K12 pupil (or student, they are so tall…)
To do so, the students will use the properties of uniform circular motion. More specifically, they will determine the radius of the circle covered by the accelerometer when the smartphone is in two different positions on a rotating disk. The intersection of the two circles will give them the position of the accelerometer in the smartphone.
The uniform circular motion is created by the rotation of a record player (33rpm).
They can use the documents for help and set up the procedure to locate the accelerometer in the smartphone. Locate it. Compare the results with the manufacturer’s specifications.
