Simple measurements & buoyancy force
Identification page
Instructions: Print this page and the following ones before your lab session to prepare your lab report. Staple them together with your
graphs at the end. If you forgot to print it before your lab, you can reproduce it by hand but you have to follow the exact
format (same number of pages, same items on each page, same space to answer question).
Complete all the identification fields below or 10% of the lab value will be deduced from your final mark for this lab.
For in-lab reports, hand in your report to your demonstrator at the end of the sessions or you will receive a zero for this lab.
For take-home reports, drop your report in the right box or 10% of the lab value will be deduced from your mark. Refer to the
General information document for the details of the late report policy.

Part 3 The buoyancy force
[4] Prepare Graph 1. Print it to a pdf file. Send the file to yourself by email or save it on a USB key. Print the graph and
attach it at the end of your report.
[1] What are the values of 𝑚 (slope) and 𝑏 (Y-intercept) in Graph 1? Provide the units.
𝑚 = ( _________________ ± _________________ )
𝑏 = ( _________________ ± _________________ )
[1] What is the apparent mass value you recorded with the setup using an electronic balance and a 500 g mass
suspended in water?
𝑚apparent = ( ____________________ ± ____________________ )
