Before you start please take note of the following recommendations/warnings:
In this laboratory we will conduct two experiments to measure the gravitational acceleration g. For each experiment you are expected to obtain your best estimate for g, including an error estimate, and compare the value you measure with the accepted value. Do they agree, or do they disagree?
In the first experiment, we will use the free fall of a picket fence to determine the gravitational acceleration. The manual for this experiment can be downloaded in pdf format by clicking here.
In the second experiment, we will use the motion of a cart on an inclined plane to determine the gravitational acceleration. In addition, we will compare the theoretical dependence of its acceleration on mass and angle with the measured dependence. The manual for this experiment can be downloaded in pdf format by clicking here.
Both experiments measure the same paramters, and you must make a comparison between both results. Do both results agree with each other? Do the results agree with the accepted value of g? Note: you will need to to a carefull error analysis in order to be able to draw any conclusions.
The laboratory report for this laboratory will be due on Friday September 22, 2023 at 12 pm. The lab reports must be submitted in pdf format using the phy141 laboratory drop box. Use the following format for the name of the lab report you are submitting: Exp#-LastName-FirstName-StudentID.pdfwhere # is the experiments number (1, 2, 3, 4, or 5), LastName is your last name, FirstName is your first name, and StudentID is you student ID number. The laboratory report should describe the results of both measurements of g. Use the guidelines in "How to write a lab report" as a starting point for your report. Make sure you include whatever graphs are needed to support your conclusions, and provide a detailed error analysis of your results.
