What is the resulting frequency of the oscillation?

Click For Summary
SUMMARY

The discussion centers on calculating the frequency of oscillation for a mass-spring system, specifically a 0.31-kg mass attached to a spring with a spring constant of 13 N/m. The correct formula for the period (T) of oscillation is T = 2π√(m/k), leading to a calculated period of approximately 0.3166 seconds. Consequently, the frequency (f) is determined using f = 1/T, resulting in a frequency of approximately 3.16 Hz. It is clarified that the displacement does not affect the period of oscillation in simple harmonic motion (SHM).

PREREQUISITES
  • Understanding of simple harmonic motion (SHM)
  • Familiarity with the mass-spring system dynamics
  • Knowledge of the formulas for period and frequency
  • Basic algebra for manipulating equations
NEXT STEPS
  • Study the derivation of the period formula for simple harmonic motion
  • Explore the effects of mass and spring constant on oscillation frequency
  • Learn about damping and its impact on oscillatory systems
  • Investigate real-world applications of mass-spring systems in engineering
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and oscillatory motion, as well as educators teaching concepts of simple harmonic motion and mass-spring systems.

Homework Statement



A 0.31-kg mass is hanging from a spring with spring constant 13 N/m. Then the mass is displaced from the equilibrium by 3.3 cm and let go.

Homework Equations



for frequencthy the equation would be 1/T


The Attempt at a Solution



to T I would use this equation 2∏sqrtm/k
2∏sqrt0.033m/13N/m= 0.316566651s

1/0.316566651s= 3.158892436Hz
I got this wrong but, this is the only equation for frequency that I was taught in class. What did I do wrong.

In the equation, 'm' stands for the mass (measured in kg); you put in the displacement (measured in meters). Fix that!
 
ok got it, but what about the displacement? does it not play a role in the equation?

Not in that equation, which is for the period. The period of oscillation (for SHM) does not depend on amplitude.
