A pendulum is made from a string that is attached to “the ceiling” in two places with a mass hanging in the middle to make a “V”.  The pendulum is pulled back a given distance and released.  The maximum speed attained by the mass is found.  This involves an equation from rotational motion (v=w r).

This is the Lab 8 Tier 2 Challenge Set-Up. This set-up presents an “error” in conducting the trial which affects the student’s result. The challenge is for the student to determine what Danny did wrong in conducting his trial and determining how the error impacted the results.
