Grade High School. Thank you for your input. Problem Build a pendulum wave apparatus. Materials 2 meter sticks or a meter stick and a ruler or tape measure 3. Starting at about the 10 cm mark on the meter stick, tie a piece of string at each point located every 9 cm along the ruler roughly. Use a small piece of tape to help secure each piece of string to the stick. Use the two book stacks to support both ends of the meter stick. Attach one weight to the free end of each string.
Thread the string through the hole or hook on each weight and, using your ruler or tape measure, adjust the lengths to exactly match the following table, starting with the longest string. Once you get the lengths right, tie the string to the weight. Let all the pendulums go at once so that they swing perpendicular to the meter stick from which they are hanging.
Enjoy the show! How many different patterns do you see? Does anything repeat? If any patterns do repeat, how long does it take for them to do so? Results The pendulum ensemble will cycle through a number of patterns over a 30 second interval.
Going Further You can modify the apparatus to add more pendulums or create a longer cycle than 30 seconds. Remember that the period of an ideal pendulum depends only on its length:. Disclaimer and Safety Precautions Education.
