5. Data Table (6 Points) Using the add
textbox button above, fill in data table below with the data from your experiment. How to find the mean / average: add a group of numbers and then
divide the sum by the amount of numbers added together. Ex: Trial 1 +
Trial 2 + Trial 3 = Sum / 3.
Data Table:
Object | Trial 1 (s) | Trial 2 (s) | Trial 3 (s) | Mean (s)
---------------------------------------------------
Piece of paper | 1.5 | 1.6 | 1.3 | 1.46
Crumpled/balled piece of paper | 0.9 | 1.1 | 1.2 | 1.07
Heavy object (such as a metal ball) | 0.5 | 0.4 | 0.6 | 0.50
sorry, i meant.
6. Conclusion (10 pts)
above, answer the questions in complete sentences
1. RESTATE your hypothesis than say whether it was incorrect or correct
1. Restating the hypothesis: The hypothesis stated that if a piece of paper, a crumpled/balled piece of paper, and a heavy object are dropped from a height of 5 meters, then the heavy object will drop the fastest.
The hypothesis was correct.
2. Next, you as the scientist need to be specific regarding whether your data supports or does not support your hypothesis. Tell me what your data showed. Give the averages. Say what it means. If you see no correlation, just say so! [FYI: it's your job to convince me even though I can read your data table. You are the 'scientist' here!] (3 points)
2. The data from the experiment supports the hypothesis. The average time for the heavy object (such as a metal ball) to drop was 0.50 seconds, while the average time for the crumpled/balled piece of paper was 1.07 seconds, and the average time for the piece of paper was 1.46 seconds. This means that the heavy object dropped the fastest, as it had the shortest average time. The data clearly shows a correlation between the weight of the object and its speed of descent, supporting the hypothesis.
3. Connect the results back to what was learned in the lessons about mass, velocity and air resistance. Why does the balled up piece of paper have different drop speeds than the flat sheet of paper if they both have the same mass. Why are drop speeds of balled up piece of paper and ball similar even though they do not have different amounts of mass? (3 point)
3. The results of this experiment can be connected to what was learned about mass, velocity, and air resistance. The balled up piece of paper and the flat sheet of paper have the same mass, but they have different drop speeds due to their different surface area and shape. The balled up piece of paper has a smaller surface area compared to the flat sheet of paper, which allows it to experience less air resistance as it falls. This reduced air resistance allows the balled up piece of paper to reach a higher velocity and drop faster than the flat sheet.
Regarding the similarity in drop speeds between the balled up piece of paper and the heavy object (such as a metal ball), even though they may have different amounts of mass, it is important to consider the effect of air resistance. Air resistance acts against the motion of objects falling through the air. In the case of the balled up piece of paper and the heavy object, their difference in mass is offset by the difference in surface area and shape. The balled up piece of paper has a smaller surface area and more compact shape, resulting in reduced air resistance. The heavy object, although having a greater mass, has a larger surface area and may experience more air resistance. As a result, the difference in mass between the balled up piece of paper and the heavy object does not significantly impact their drop speeds, as the effect of air resistance plays a more dominant role in this scenario.
