Investigating the Oscillations of a Pendulum

Examine the purpose of the vibration of the pendulum. - Examine the vibration of a simple pendulum and find the value of "acceleration" caused by "gravitational acceleration" in the laboratory. Apparatus: - Distillation bracket with clamp Pendulum a yarn (≥ 110 cm) stopwatch Rule and theory of two small wooden block gauges: - In this experiment the following settings were adjusted.

Examine the purpose of the vibration of the pendulum. - Examine the vibration of a simple pendulum and find the value of "acceleration" caused by "gravitational acceleration" in the laboratory. - Use the pendulum to find the gravity goal. Find the gravity by finding the cycle of the pendulum vibration and drawing a graph. Assumptions and predictions: - The gravity of the graph equals the gravity of the equation

The pendulum is suspended at a fixed point so that the body can swing back and forth under the influence of gravity. The pendulum is used to adjust the movement of the watch. Because the time interval of each complete vibration (called period) is constant. Italian scientist Galileo first pointed out the constant nature of the pendulum cycle by comparing the movement of the shaking light of Pisa Cathedral with his pulse rate (c.1583). In 1656, Christian Huygens, a mathematician and scientist in the Netherlands, invented a clock controlled by the pendulum movement. Priority of the pendulum invention was called Huygens by some authorities and other agencies, but Huygens solved the basic problem of the manufacturing industry. By designing the pivot so that the suspended body or pendulum swings along the cycloidal arc rather than the arc, the period of the pendulum does not change.

In 1656, Dutch scientist Christiaan Huygens made the first pendulum clock. (Galileo Galilei has been acclaimed for inventing the concept of pendulum, he studied the movement of the pendulum as early as 1582. The early pendulum clock has an error of less than 1 minute a day, and It is the first time that such accuracy has been achieved, but his subsequent refinement reduced his clock error to less than 10 seconds per day.
