Abstract

This study aims to experimentally verify Hooke’s Law and examine the elastic characteristics of a metal spring within its elastic region. A laboratory experimental method with a descriptive quantitative approach was employed by applying incremental loads of 50–80 g, where each load was measured through three repeated trials (n = 3) to improve data reliability. The resulting elongation was analyzed using linear regression between applied force and elongation. The results show a strong linear relationship, yielding an average spring constant of approximately 2.9 N/m, with the regression equation and a coefficient of determination close to 1.00, indicating high linearity. Measurement uncertainties arose primarily from instrument resolution (±0.5 mm) and possible parallax errors; however, these variations remained within acceptable limits and did not significantly affect the linear trend. These findings confirm that the spring operated within its elastic region and empirically support Hooke’s Law. The study also highlights the pedagogical value of experimental activities in enhancing students’ understanding of elasticity concepts and awareness of measurement uncertainty.

Abstract

Language is the primary means of communication used by humans to convey ideas, thoughts, and feelings in social life. In the Indonesian context, the Indonesian language plays an important role as both the national language and the official state language, functioning as a unifying tool for a society with diverse cultural backgrounds and regional languages. This study aims to conceptually examine the definition of language and the characteristics of the Indonesian language from a linguistic perspective. The research method employed is a qualitative approach using a library research design through the analysis of various relevant scientific literature sources. The results of the study indicate that the Indonesian language possesses several main characteristics: it is systematic, arbitrary, productive, dynamic, and conventional. These characteristics demonstrate that Indonesian is a structured linguistic system capable of developing in accordance with the communication needs of society. Therefore, understanding the concepts and characteristics of the Indonesian language is essential to support proper and correct language use in various fields of life, particularly in education and academic communication.
