Use the table of data from an investigation on the effect of gravity on falling objects to answer the question.
Student Ball 1 (seconds) Ball 2 (seconds) Ball 3 (seconds)
Ziva 0.52 0.51 0.51
Jade 0.51 0.52 0.52
Eduardo 0.50 0.50 0.50
Owen 0.50 0.37 0.51
Four students investigated the effect of gravity on falling objects. The students all used the same three balls and dropped them from a height of 8 meters. They recorded the time it took for each ball to hit the ground. Which student most likely had an error in the results?
A.) Owen
B.) Eduardo
C.) Ziva
D.) Jade
A.) Owen
To determine which student most likely had an error in the results, we can compare the recorded times for each student.
Looking at the data, we see that Eduardo recorded consistent times of 0.50 seconds for all three trials. Ziva and Jade also recorded consistent times of 0.51 and 0.52 seconds respectively for all three trials.
However, Owen's recorded times vary significantly, with a time of 0.50 seconds for the first and third trials, but a time of 0.37 seconds for the second trial.
Based on this inconsistency in Owen's results, it is most likely that he had an error in his data recording.
Therefore, the student who most likely had an error in the results is A.) Owen.
To determine which student most likely had an error in the results, we can analyze the data presented in the table. The students dropped the same three balls from the same height and recorded the time it took for each ball to hit the ground.
From the data, we can observe that there are slight variations in the recorded times for each ball among the students, but the times for each ball should ideally be similar for all students if the experiment is conducted accurately.
Looking at the data, we see that Ball 1 consistently took around 0.51 to 0.52 seconds to hit the ground for most students. This suggests that Ball 1's time is reliable.
However, for Ball 2, Eduardo's recorded time is consistently 0.50 seconds, while the other students have recorded times of 0.37 and 0.52 seconds. This discrepancy in Eduardo's results for Ball 2 indicates the possibility of an error.
Therefore, the student most likely to have an error in their results is B.) Eduardo.
