Fun Cycloid
★Exhibit Content: Amplitude and Frequency ★Interaction: Mechanical Interaction ★Operation: 1. Push the lower lever to adjust the pendulum to its longest length; 2. Push the upper toggle to make the pendulum swing; 3. Pull the lower lever to shorten the pendulum length and observe the changes in swinging. ★Exhibit Description: The exhibit consists of slide rails and spring steel sheets, etc. Flick the spring steel sheet, move the handle, and gradually shorten the length of its vibrating part; you will find that its vibration frequency becomes faster and faster, while the vibration amplitude becomes smaller and smaller. The exhibit demonstrates the physical quantities that describe the vibration state of an object: amplitude and frequency. Amplitude is numerically equal to the maximum displacement during vibration, while frequency is the number of complete vibrations completed per unit time. Amplitude and frequency respectively determine the loudness and pitch of sound. ★Scientific Principle: Make a simple pendulum, gently swing it, and let it swing with a small initial swing. Then pull the movable end of the string to shorten the length of the pendulum, and you will find that the swing frequency becomes faster and faster. If the length of the pendulum is reduced to 1/4 of the original, the swing period will be reduced to 1/2. By measuring the swing time dozens of times, the experimenter will see that no matter whether one, two, or more pendulums are hung on the string, as long as the length of the string remains unchanged, the swing period will not change at all, and the swing frequency is inversely proportional to the pendulum length. The longer the pendulum length, the lower the swing frequency. Conversely, the shorter the pendulum length, the higher the swing frequency. In this exhibit, by shortening the length of the elastic pendulum, you will find that the elastic pendulum moves faster and faster. In daily life, when playing musical instruments, different sounds are also produced by changing amplitude and frequency.
