Experiment with the Pendulum Applet in order to answer the following questions

# 1.

The PERIOD of a pendulum is defined as the amount of time it takes for the pendulum to make one complete cycle. However, some people are confused about that definition. Assume the pendulum starts on the right and swings to the left and then back to the right. Is the PERIOD the amount of time it takes to get from the right to the left -- or is it the amount of time it takes to get from the right to the left and back to the right where it started? That is easy, a complete cycle must get you back to the starting point. So, if it started on the right, it must end on the right.

Set the pendulum to be 6.2 cm long and measure the period. Write your answer in the box below.

# 2.

Now, consider how we could be more accurate. It was probably difficult to measure the period because the pendulum was swinging so rapidly. How could you improve your accuracy? Think about it and write your answer in the box below.

# 3.

Now increase the length of the pendulum and measure the period. Do this several times and then answer the following question: As the length of the pendulum increases, the period (increases- decreases - remains constant - changes irregularly). Write your answer in the box below.
