Physics · Experimental Physics and Data Analysis
A group of students uses a smartphone accelerometer to study elevator motion. The data shows small oscillations around zero even when the elevator is stationary. Which of the following responses reflects true experiential reasoning?
- 1Re-run the experiment with airplane mode on, as signals interfere with sensors
- 2Discard the noisy data before interpretation
- 3Understand that micro-vibrations and sensor sensitivity create measurable fluctuations✓
- 4Assume the phone sensors are defective
Correct answer
Understand that micro-vibrations and sensor sensitivity create measurable fluctuations
