(Reference M-J/2012/12),i am confused in choosing A and D Q. A mass is dropped from rest, and falls through a distance of 2.0 m in a vacuum. An observer<br />records the time taken for the mass to fall through this distance using a manually operated<br />stopwatch and repeats the measurements a further two times. The average result of these<br />measured times, displayed in the table below, was used to determine a value for the acceleration<br />of free fall. This was calculated to be 9.8ms–2.<br /> first measurement second measurement third measurement average<br />time/ s 0.6 0.73 0.59 0.64<br />Which statement best relates to the experiment?<br />A The measurements are precise and accurate with no evidence of random errors.<br />B The measurements are not accurate and not always recorded to the degree of precision of<br />the measuring device but the calculated experimental result is accurate.<br />C The measurements are not always recorded to the degree of precision of the measuring<br />device but are accurate. Systematic errors may be present.<br />D The range of results shows that there were random errors made but the calculated value is<br />correct so the experiment was successful.
