The measurement of Rachel’s group is precise but not accurate while the measurement of Ashley’s group is accurate but not precise.
Precision has to do with how close together the values obtained from a scientific measurement is. If we take a look at the values obtained by Rachel’s group, we will notice that the values are exactly 1.00 g apart. This means that the values are precise.
However, these values a far from the actual value which is 100.00 g therefore the measurement of Rachel’s group is precise but not accurate.
On the other hand, the values obtained by Ashley’s group are; 99.5 g, 100.1 g, and 100.5 g. These values are very close to the actual value which is 100.00 g hence they are accurate.
The values obtained by Ashley’s group do not have consistent intervals therefore, they are not precise.

Answer:
Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. A feather and a rubber ball dropped together. Air resistance causes the feather to fall more slowly, while the ball falls more fast.
