Please consider this released STAR test question:

A student does an experiment to measure the acceleration of a falling object, which is 9.8 m/s². The student obtains an experimental value of 14.6 m/s². The reason for this variation is most likely due to

1. human error.
2. air resistance.
3. local fluctuations in gravity.
4. the mass of the object.

Announcement:

There will be a 45 minute peer-to-peer tutoring session at 3PM on Tuesday, in preparation for the Unit 1 Quiz on Thursday/Friday. Students will sign in, and receive 1 extra credit point. The quiz will contain materials from Chapters 1-3, as well as any other topics covered in class.
