The simple pendulum, a fundamental concept in classical mechanics, offers profound insights into the principles governing oscillatory motion. This lab report delves into an experimental exploration of the simple pendulum to understand how its period is influenced by various factors such as length, mass of the bob, and amplitude of swing. Through meticulous observation and analysis, this study aims to verify the theoretical relationship between the pendulum's period and its length, thereby enriching our understanding of harmonic motion.
A simple pendulum consists of a weight (bob) suspended from a pivot point, allowing it to swing freely under the influence of gravity.
The period of a pendulum, or the time it takes to complete one full oscillation, is a subject of interest because of its dependence on physical properties like the length of the pendulum (L) and the acceleration due to gravity (g), but notably not on the mass of the bob or the amplitude of swing, assuming small angles.

The theoretical formula for the period (T) of a simple pendulum is given by:
The experiment's primary objectives were: i) To determine the relationship between the pendulum's length and its period. ii) To observe the impact of bob mass and swing amplitude on the pendulum's period. iii) To compare experimental results with theoretical predictions.
This process was repeated for multiple lengths.
The data collected from the experiment provided valuable insights into the behavior of the simple pendulum under different conditions.
The experimental findings corroborate the theoretical model of the simple pendulum, particularly the square root relationship between the pendulum length and its period. The independence of the period from the bob's mass and the amplitude of swing, within small angles, further validates the foundational principles of pendular motion.
While the experiment successfully demonstrated the primary characteristics of pendular motion, certain limitations were present, such as air resistance and the precision of time measurement, which could slightly deviate the results from theoretical expectations.
This comprehensive exploration of the simple pendulum through experimental analysis substantiates the theoretical predictions concerning the pendulum's period and its dependence on length, while affirming its independence from mass and amplitude within practical limits. The experiment not only enhances our understanding of harmonic motion but also highlights the significance of empirical investigation in corroborating theoretical physics models. Future studies could focus on quantifying the effects of external factors like air resistance on the pendulum's motion, offering a deeper insight into the complexities of real-world oscillatory systems.
