Pengaruh Massa dan Konstanta Pegas terhadap Periode Getaran: Eksperimen dan Analisis Data
The study of simple harmonic motion is fundamental in physics, providing insights into the oscillatory behavior of various systems. One of the key aspects of this motion is the period, which represents the time taken for one complete oscillation. This period is influenced by several factors, including the mass of the oscillating object and the stiffness of the spring. This article delves into the relationship between these factors and the period of oscillation, exploring the results of an experiment designed to investigate this relationship. <br/ > <br/ >#### The Experiment: Investigating the Relationship Between Mass and Period <br/ > <br/ >The experiment involved a simple setup consisting of a spring attached to a mass. The mass was then displaced from its equilibrium position and allowed to oscillate freely. The time taken for a specific number of oscillations was measured using a stopwatch, and the period was calculated by dividing the total time by the number of oscillations. This process was repeated for different masses, while keeping the spring constant. The data collected was then analyzed to determine the relationship between mass and period. <br/ > <br/ >#### The Relationship Between Mass and Period <br/ > <br/ >The analysis of the experimental data revealed a clear relationship between the mass and the period of oscillation. As the mass increased, the period of oscillation also increased. This relationship can be explained by considering the forces involved in the system. The restoring force exerted by the spring is proportional to the displacement of the mass from its equilibrium position. However, the inertia of the mass, which is directly proportional to its mass, resists this restoring force. As the mass increases, its inertia increases, leading to a slower acceleration and a longer period of oscillation. <br/ > <br/ >#### The Experiment: Investigating the Relationship Between Spring Constant and Period <br/ > <br/ >In the second part of the experiment, the mass was kept constant, and the spring constant was varied. This was achieved by using springs with different stiffness values. The same procedure of measuring the time for a specific number of oscillations was repeated for each spring. The data collected was then analyzed to determine the relationship between the spring constant and the period of oscillation. <br/ > <br/ >#### The Relationship Between Spring Constant and Period <br/ > <br/ >The analysis of the experimental data revealed an inverse relationship between the spring constant and the period of oscillation. As the spring constant increased, the period of oscillation decreased. This relationship can be explained by considering the restoring force exerted by the spring. A higher spring constant indicates a stiffer spring, which exerts a stronger restoring force for a given displacement. This stronger force leads to a faster acceleration and a shorter period of oscillation. <br/ > <br/ >#### Conclusion <br/ > <br/ >The experiment demonstrated the influence of mass and spring constant on the period of oscillation in a simple harmonic motion system. The period of oscillation was found to be directly proportional to the square root of the mass and inversely proportional to the square root of the spring constant. These findings are consistent with the theoretical predictions based on the equations of motion for simple harmonic motion. The experiment provides a practical understanding of the factors that affect the period of oscillation, which is crucial for understanding the behavior of various physical systems, including pendulums, springs, and musical instruments. <br/ >
