A family brought their grandfather clock from Denver, Colorado to Clarksville, TN when they moved. Shortly afterwards, they discovered that the clock no longer ran accurately due to a change in the local g value. Do you expect the clock runs faster or slower? How do you fix the problem, moving the oscillating piece up or down?

The clock runs faster. Moving the oscillating mass up slightly so the rod is shorter. The clock runs slower. Moving the oscillating mass down the rod slightly so the rod is longer. 1. Yes. 2. No.
