Experimental Scenario
Donna has observed that her father can control the speed of their grandfather clock by adjusting the

when the weight is lowered, and wants to test her idea. Donna gets a stopwatch and measures the
time it takes for the pendulum to swing twenty times when the weight is moved to its lowest position.
Donna begins to move the pendulum up by 1 cm and continues to measure the time for twenty swings
of the pendulum. Donna records her data
