You completed the practical aspect of your LO3 task today.
For next week, please process your data so you can show me
- complete table of results
- a graph of centripetal force vs the square of angular velocity
- sample calculations for your uncertainties.
This will probably be easier to complete if you use a spreadsheet program such as Excel or OpenOffice. You will need diagrams for the procedure section of your LO3 report. Scanned images of the apparatus are available here.
