Contribution

It provides a detailed analysis of how a spring's mass influences harmonic oscillations, offering insights beyond the traditional massless spring model.

Findings

Spring mass significantly affects oscillation frequency.

Mass distribution alters the effective oscillation dynamics.

Results improve understanding of real-world spring behavior.

Abstract

Springs are used in simple demonstrations for the students of Physics classes to illustrate the Hooke's Law and harmonic oscillations. The spring is usually considered as a light object that does not possess a mass. What happens if the spring is heavy, that is, if its mass is not negligible? This paper aims to discuss this problem as plainly as possible.
