PHYSICS DISCUSSION QUESTIONS

Would your results be the same if you had used the duct tape side of the block instead of the wood? Explain.

The results would not be the same since duct tape has a different friction from wood. This is because wood has a more uneven and rough texture, while duct tape is smoother.

If all 4 sides of the block (ignoring the 2 ends of the block) were the SAME material, would it matter which side you placed the block on? Explain why or why not.

No, it wouldn’t matter because the friction is the same. This is because the mass has not changed, and the material has also not changed.

Should your results for be the same for each trial, or different? Explain.

The results should be the same because the material and mass is still the same. Since friction is the same for each the result, the coefficient of friction in each of the trials should match. However, the experimental values were different due to human error.

Error Analysis

The experimental values of experiment 1 and 2 was 64.6%. This is quite a large value because we likely made multiple human and experimental errors. Most of the errors probably occurred in experiment two because it had the largest value for the coefficient of friction. The percent value of experiment 1 and 2 was 34.2%, which is a medium value. Human and experimental errors in experiment three likely resulted in a greater coefficient of friction value, but the percent difference is not as drastic as the percent difference for experiments 1 versus 2. Lastly, the percent difference of experiments 2 and 3 was the smallest value: 32.2% Nevertheless, this is still a medium-sized value for percent difference, which was likely caused by human error in both experiments. However, this value is smaller than the others since the experimental value for the coefficient of friction for both experiments were larger than the value in experiment

    I’m going to talk about other researcher experiment on “How long would it take to get to the center of the Tootsie Roll Pop”. Also my point of view on what I think about their say on their experiment about “How long would it take to get to the center of the Tootsie Roll Pop”. On the Tootsie Roll web page they had three scientific studies that have attempted to determined on how many licks it take to get to the center of the Tootsie Roll Pop. The first one is from a Purdue University where a “A group of engineering students from Purdue University reported that its licking machine, modeled after a human tongue, took an average of 364 licks to get to the center of a Tootsie Pop. Twenty of the group's volunteers assumed the licking challenge-unassisted by machinery-and averaged 252 licks each to the center”.

    Our lab results on all three data table experiments had a percent error less than 5 percent. When examining these results I can be almost certain it was not systematic error due to the fact that a major percent error was not detected on every trial that was run in each of the three tables. With there being some percent error there is the possibility for random error which are from unknown factors, which could come from impact of outside forces like the air track interfering with the acceleration of the cart. Beings that this was the first lab for my lab partners and I were working there was room for slight personal errors with our use of the computer program as well as the lab equipment.

    All the experiment was depending on fortune and luck and can not be successful at all because the performers do not have proper direction to perform the experiment. For the experiment, workers should have proper equipment, standardise and should have power to do work their own way. It is also concluded that the quality of production might be great in future by use the present statics and create a quality control chart and solve the problem in specific problems which effects the project. The common wisdom is that if only people did not make so many mistakes, there would not be so many problems. But even with the variation contributed by the people reduced to zero, there are still too many red

  • AP Physics Class Reflection

    Westchester High School has always offered a limited number of honors and advanced placement courses. Last year, to my dismay, only Mr. P. was teaching the AP Physics class I had my heart set on. From my peers, I had heard that he was an unskilled teacher because of his poor classroom management and lack of instructional time. Taking this class was very important to me because I enjoyed science, wanted a challenge, and hoped to get AP credit. So beforehand, I already knew that I would have to learn AP Physics on my own, but since I have had experience with terrible teachers before, I felt that I could handle the class and was ready for the challenge.

  • What Happens When Can Yeast Metabolize?

    For example, in the response experiment, a yeast solution was prepared without sugar mistakenly and thus had to be prepared again. This suggests that other errors in preparation and measurement could have been encountered. For the future, careful measurements using clean uncontaminated flasks would eliminate possibilities of such error. A source of error for the metabolism experiment involves the yeast’s yellow hue. It is possible that the color of the yeast caused the solution to look more
