Experimental Scenario
Donna has observed that her father can control the speed of their grandfather clock by adjusting the
height of the weight on the end of the pendulum. Donna thinks that the pendulum will move faster
when the weight is lowered, and wants to test her idea. Donna gets a stopwatch and measures the
