Relationship betwen SHM frequency and harmonic oscillator freq.

Click For Summary
SUMMARY

The discussion clarifies the relationship between the frequency of a harmonic oscillator, specifically a spring, and that of a simple harmonic oscillator, such as a pendulum. The formula for the frequency of a pendulum is given as f=(1/(2∏))√(g/L). It is established that while both systems exhibit harmonic motion, a spring can experience damping, which disqualifies it from being classified as a simple harmonic oscillator under certain conditions. This distinction is crucial for understanding the dynamics of oscillatory systems.

PREREQUISITES
  • Understanding of harmonic motion principles
  • Familiarity with the formula for pendulum frequency
  • Knowledge of damping effects on oscillators
  • Basic physics concepts related to forces and motion
NEXT STEPS
  • Study the derivation of the frequency formula for springs and pendulums
  • Explore the effects of damping on harmonic oscillators
  • Learn about the conditions for simple harmonic motion
  • Investigate real-world applications of harmonic oscillators in engineering
USEFUL FOR

Students studying physics, educators teaching harmonic motion, and anyone interested in the principles of oscillatory systems.

Homework Statement



Relate the frequency of a harmonic oscillator (spring) to that of a simple harmonic oscillator (pendulum) Show all derivations.



Homework Equations



pendulum:
f=(1/(2∏))√(g/L)



The Attempt at a Solution



Not exactly sure how to go about this...is it saying that a spring isn't a SHM...because I thought it was. Please help me understand!

hi songbird7! welcome to pf! :smile:

i think they're getting at the distinction mentioned in wikipedia
If F is the only force acting on the system, the system is called a simple harmonic oscillator …​

since a spring can be damped, its motion wouldn't be simple harmonic :wink:
