1.First of all:
The purpose of this assignment is to demonstrate that you can investigate and analyze physical phenomena by applying relevant concepts in practice and draw your own conclusions based on your own experimental data.
For virtual (computer-based) laboratories, you will be asked to perform experiments using online University of Colorado PhET simulations of experiments related to the module’s syllabus (e.g. “Mass and Spring”).
Objective – Use algebraic and graphical methods to study the relationship between mass m and period of oscillation T and determine the value of spring constant k with uncertainty.
Five. If this procedure is performed in a laboratory/classroom, please include a risk assessment in your report.
Results (5 points): The results shown in the table and all other relevant results. Uncertainties and errors (such as instrument uncertainties, random errors, zero errors, etc.) that are all clearly, precisely and accurately recorded and correctly presented. For tables, column headings should include uniformity and uncertainty. The table should contain approximately 8 rows. No fabricated results!
Chart (5 points): Choose a descriptive title and carefully label both the x- and y-axes with quantities and units. Draw a best-fit line (do not connect the points) and measure the slope of the best-fit line itself (do not use the drawn points for the slope; do not use values that correspond directly to the result table. please). If you calculate the slope directly, you should draw a large triangle on the graph to clearly indicate the accuracy of the slope calculation. If there is an abnormality, please circle it.
Analysis (10 points):
Conclusion (5 points):
Begin your conclusion by stating your final results. This must be presented in the correct format: k = (….. ± â€.) units. Then compare the result with the theoretically expected value along with the tolerance (use ± to find the two extreme values: is the value you looked at within the range?) Information on which the theoretical value is reliable Cite the source to show that it is from the source (provide a reference to the website or VLE of the book where you found the theoretical value in the bibliography). Finally, explain in your scientific report the main reasons why the results do not match 100% with the theoretically expected values (what do you think are the main sources of error?).
Evaluation (5 points):
Please describe in detail what worked and what did not work for the measurements you performed and the equipment you used. Identify and discuss as many random and systematic errors as possible and list suggestions for improvements so that next time these errors and uncertainties can be minimized.
References (2.5 points):
Harvard University should be mentioned here. Please include any websites or books you used, such as: B. VLE (for virtual labs, you must specify the PhET simulation used), providing a source of theoretical expectations
