Measuring Gravitational and Inertial Mass
Note: you must design the details for this experiment yourself: it is not a cookbook experiment.
Goal: Determine whether a difference exists between gravitational and inertial mass.
- Equal arm balance
- Standard masses
- Sample masses
Inertial balance or spring-loaded pan balance. You will have to devise this. An example of an inertial mass scale is shown in this YouTube Inertial Mass Lab video. The key feature of the inertial mass detection device is that it must be able to vibrate or bounce.
- Read through this PhysicsLAB's Gravitational vs. Inertial Mass description. Determine how you will measure each type of mass and write up a plan for your procedure.
- Plan the table for your gravitational mass data. How will you measure gravitational mass? What units will you use? What data will you collect? What calculations will you need to make?
- Plan the table for your inertial mass data. How will you determine inertial mass from the data you collect? What units will you use for your observations? What calculations will you need to make?
