Suppose that a grandfather clock (a simple pendulum) is running slowly. That is, the time it takes to complete each cycle is longer than it should be. Should one shorten or lengthen the pendulum to make the clock keep the correct time? Why?

The period of a pendulum is proportional to the square root of the length of the pendulum. You want it to "tick" (swing back and forth) faster. What does that tell you?

Lengthening the pendulum will increase the frequency and make it run faster
