Abstract:
|
Accelerometers such as found in smartphones respond to both acceleration caused by contact forces, and also to the gravitational field intensity when not accelerating. (When the device is accelerating in free-fall, the reading is zero.) The resulting measurements from the "smart" devices have been incorrectly reported as the acceleration several times in The Physics Teacher. Strategies for correcting this misunderstanding of acceleration will be discussed.
