1. 1.

   A student investigates how the acceleration of a glider on a frictionless air track depends on the net applied force while keeping the glider's mass constant. For net forces of 2.0 N, 4.0 N, 6.0 N, 8.0 N, and 10.0 N, the recorded accelerations are 0.81 m/s², 1.59 m/s², 3.75 m/s², 3.22 m/s², and 3.98 m/s², respectively. Based on scientific data analysis, which statement best explains how the student should interpret this data set before formulating a final conclusion?

   • A) The data confirms an inverse relationship between force and acceleration because the rate of change fluctuates across consecutive trials.
   • B) The student should discard the trial at 10.0 N because greater forces introduce inherently unreliable instrument calibration errors.
   • C) The student should compute the arithmetic mean of all five recorded acceleration values to report a single representative acceleration.
   • D) The measurement at 6.0 N is an anomalous outlier that deviates from the approximately linear trend, so it should be re-examined or repeated.
