Abstract

Pendulum-derived gravitational acceleration values vary unpredictably due to unquantified string length and initial angle dependencies. This study aims to assess the feasibility and precision of the mathematical pendulum swing method in measuring gravitational acceleration. The research investigates the relationship between the pendulum’s string length, oscillation period, and initial deviation angle. It is hypothesized that longer strings will result in slower oscillations while shorter strings produce faster motions. Additionally, the study examines how these factors collectively impact gravitational acceleration measurement. Through controlled experiments, the study’s goal is to determine the precision of the pendulum swing method in determining gravitational acceleration and the factors influencing its reliability. Results demonstrate that a simple mathematical pendulum accurately determines gravitational acceleration with a calculated value of approximately 9.95974m/s². The findings confirm that the square of the oscillation period is directly proportional to the string length (T² ∝ l) and emphasize the importance of maintaining the initial deviation angle under 10 degrees to ensure measurement accuracy. These findings reinforce the pendulum’s utility in physics education and affordable gravitational field assessment, particularly in resource-limited settings. The study provides a foundational framework for improving experimental accuracy in classical mechanics and highlights the method’s enduring relevance in scientific pedagogy and fundamental research.

Abstract

Background: Giant congenital melanocytic nevus (GCMN) is a rare condition present at birth, with an estimated incidence of fewer than 1 in 20,000 live births. While smaller congenital melanocytic nevi are common, GCMN poses significant clinical concerns due to its potential malignant transformation into melanoma. Early recognition and long-term monitoring are crucial to mitigate risks. Objective: This case report aims to highlight the clinical presentation, diagnostic approach, and management challenges of GCMN to emphasize the importance of timely intervention. Case Presentation: A 24-year-old male presented with a progressively enlarging blackish facial lump that bled upon scratching. Laboratory tests indicated leukocytosis, and histopathology confirmed tumor growth in the epidermis with papillomatous architecture and hyperkeratosis, leading to a diagnosis of GCMN in the fronto-nasal region. Result: The histopathological findings confirmed GCMN, underscoring the need to its malignant potential. Despite its benign appearance, the lesion’s progressive growth and bleeding tendency warranted close monitoring. Conclusion: GCMN, though rare, requires early detection, appropriate treatment, and lifelong surveillance to prevent malignant transformation. Delayed intervention, often due to cosmetic concerns, may increase complications. Thus, a multidisciplinary approach involving regular follow-ups is essential for optimal patient outcomes.
