12 Oct: Lab  Unknown mass

Problem: Find mass of a (key – or other object) without directly weighing it.

• Must use simple machine, inertia, cantilever, etc., to obtain mass

• You only have one know mass to start with

 EC if you can do it two ways and if at least one is original (no one else is doing it like you)

 Hypothesis: (yours)

Material:

1. one known mass,

2. string, pulley, rubber bands, clamps, meter-stick, ring-stand, stopwatch, thin bar/stick that bends a little, etc.

Procedures: (yours)

Data:  (yours)

In Conclusion: (yours --> make sure to use supporting data)

Make sure that you address % error and show calculations
