- This is a formal lab.
- The purpose of this lab is to investigate the difference between
inertial mass, gravitational mass and weight.

an image from the web.
Use proper citations!

to describe it. Is it linear? What does the equation
tell you? What does the slope mean? What does the y-intercept
mean?
- Experiment 1: inertial mass vs. gravitational mass
- Measure the inertial mass of the unknown mass using your
inertial balance and the equation from your graph.
- Measure the gravitational mass of the unknown mass using
a triple beam balance.
- How did your inertial mass measurements compare to your
gravitational mass measurements? Find the percent
difference between the two.
- What is the difference between inertial mass and gravitational
mass? Are they equivalent? How can you tell?
- Experiment 2: mass vs. weight round 1
- Hang your slug from the bottom of the tray with some string.
Now the balance is supporting its weight, but the mass is not
in the tray.
- Try to determine the mass of the slug. Is it different from
before? Is the inertial balance able to measure the mass when
set up this way? Explain in terms of the Law of Inertia.
- Are mass and weight equivalent? How can you tell? Justify
your answer based on the results of your experiments.
- Experiment 3: mass vs. weight round 2
- Support your slug with string such that it is in the
hole of the inertial balance, but its weight is not being
supported by the tray.
- Determine the inertial mass of the slug with it set up
this way. Is it different from when the slug just sat
in the tray? Can the inertial balance measure the mass without
supporting the weight?
