Lab Report 1 Group members: ● Sophia Mei ● Laura Mezny ● Nishi Patel ● Stephanie Urena 1. Introduction: Introduce your experiment by briefly describing the question your group is answering or the phenomenon that you are exploring. Why did your group choose this specific measurement? If relevant, provide any physics background information needed to understand the experiment. Our experiment is to explore how different magnitudes of applied force change the acceleration of the device. We chose this to connect Newton’s Laws to acceleration to better understand the new lecture topic. Newton’s 2nd Law mentions how external force is equal to the mass multiplied by the acceleration. By keeping mass constant and changing the external force, we can see how acceleration is impacted. 2. Methods: Describe the procedure of your experiment. It may be helpful to include diagrams or photographs. To test this hypothesis, we measured how much the acceleration changed when we flicked the io lab to move compared to when we pushed the io lab from the same starting point to the same end location designated by a box. The following are each of the steps we conducted to get our data: 1. Calibrate the IOlab for force and acceleration 2. Set 2 levels of increasing force to be independent variable 3. Push the IOLab device with increasing force 4. Record the acceleration for each force 5. Analyze the data 6. Go back to the hypothesis and check if the results match our debunk theory. 3. Results: Record the data from your experiment. This may include IOLab graphs or tables with numerical measurements. Make sure to include units on your measurements, as appropriate. You should present your data clearly before trying to describe or interpret it. This week: Make sure to include a screen capture showing the data from the IOLab software. The image in your report should be zoomed in properly to show the important details of your measurement. See the bottom of this handout for an example of what a good and bad zoom looks like.

4. Analysis: Use words to describe the results of your measurement. What observations do you make about them? If relevant, do you see any patterns? Do not try to explain your data yet. In our experiment, we found that when we pushed the iOLab, there was a difference in the amount of acceleration at the beginning compared to when we just flicked the iOLab. The acceleration was much greater when pushed with more force than when it was flicked with much less force. We could conclude this because the area under the curve for acceleration increases as the force increases. In trial one approximately 0.009 N force was applied and the approximate maximum acceleration was 0.160 m/s^2 whereas in trial 2 when we applied an increasing force of 0.032 N was applied we got the resulting acceleration of 1.019 m/s^2. This brings us to the conclusion that when we increase the force the acceleration of the object increases as well. 5. Discussion: Try to explain your result. Is it interesting or surprising? Why? Does it suggest any trends or physical properties? This is not interesting or surprising as it follows the equation force/mass = acceleration, as the mass of the iOLab is not changing but the force applied to it is. As the force increases, the acceleration also increases because force and acceleration are directly proportional. This was also the expected result because as Newton's Law says F=ma. 6. Conclusions: Briefly summarize your experiment and your findings. If you think there is more to explore about your measurement in further experiments, talk about it here. We found that when we pushed the iOLab with more force, the initial acceleration is much more than when we pushed the iOLab with less force. This demonstrates how force and acceleration are directly proportional. There can be more to explore with the measurements as you could see how adding a mass atop the iOLab could affect the acceleration such as slowing it down. Work Summary: Sophia worked on the introduction Nishi worked on the method and analysis Stephanie collected the data Laura helped write the discussion and the conclusion.
