Section: General Physic Lab 3
The goal of this experiment was to learn how to apply computerized instruments in physics. In addition, this experiment aimed at enhancing practice on how to use three equipment in the lab: the rotary motion sensor, high resolution force sensor, and motion sensor. Further, this experiment sought to clarify the circumstances under which the instruments fail to comply with expectations.
Part 1: The Motion Sensor
Motion Sensor’s Measurement of Distance on ‘Short Range’ 1 m
Closest Measurable Distance on ‘Short Range’ 0.12 m
Closest Measurable Distance on ‘Long Range’ 0.12 m
Distance from Center Line for First Detection of Block on ‘Short Range’ 0.05 m
Distance from Center Line for First Detection of Block on ‘Long Range’ 0.055m

Equally, a reading of 1.00m was obtained when measured on the short range setting (Table 1). The percentage deviation was negligible, at 0 %. A correction factor was applied while calculating the subsequent 1-m distances that were used to compute the range of the motion sensor. This ruled out any possibilities of discrepancies, suggesting that the experiment was conducted with a high degree of precision and accuracy.
With the Motion Sensor set on ‘Short Range’, it got as close as 0.12 m to a target before incorrect readings are shown. This distance was determined from the point where the motion sensor moved towards the distance where no readings could be obtained after which, it reversed to the 1-meter distance where the readings were picked up by the sensor. This trend is illustrated in Figure 2 where the graph bottoms and levels out on the parabola before rising up once more.
When the Motion Sensor was set to long range, the closeness to the target was no different from the ‘short range” setting, that is, 0.12 m. Afterwards, the readings became
