Accelerometer
Making and Improving a Simple Accelerometer
-string and washer
Test it in a variety of situations
Problems
1. circular instead of planar motion
2. can't read it when it swings (where was top?)
3. broke, tangled, lost
4. no scale or way to capture instantaneous (ie. max) acceleration
5. not enough swing space (arm too short to keep iwasher at eye level)
Make (or diagram and describe) Improvements
