Which Spring Constants to Use for Magnet Oscillation Experiment?

Click For Summary
SUMMARY

This discussion focuses on determining the appropriate spring constants for an academic research project involving the oscillation of magnets attached to extension springs. The researcher seeks to identify 10 different spring constants suitable for a load of approximately 40 grams to achieve a range of oscillatory data. The conversation emphasizes the need for clarity regarding the specific oscillatory behavior being studied, particularly in vertical spring-mass systems, and questions the choice of magnets over traditional weights.

PREREQUISITES
  • Understanding of Hooke's Law and spring constants
  • Knowledge of oscillatory motion and frequency in spring-mass systems
  • Familiarity with experimental design in physics research
  • Basic principles of magnetism and its application in experiments
NEXT STEPS
  • Research the calculation of spring constants using Hooke's Law
  • Explore the dynamics of vertical spring-mass systems and their oscillatory behavior
  • Investigate the effects of varying loads on spring oscillation frequency
  • Examine the use of magnets in experimental setups and their advantages over weights
USEFUL FOR

Physics students, researchers in experimental mechanics, and anyone conducting studies on oscillatory systems involving springs and magnets.

For my academic research project, I am studying the oscillatory of magnets attached to extension springs. And to have variety of data on different types of oscillation, I'll be using different spring constants as a variable. But in order to get the springs I need to know the dimensions of the specific springs. Therefore, what are the 10 different spring constants that I should have for ascendingly varying oscillations of spring for a load of around 40 grams?

Please be more specific. What exactly is the "oscillatory of magnets attached to extension springs"? Are you talking about the frequency of oscillations in vertical spring-mass systems? If so, why use magnets and not plain weights? What are you going to measure? In projects of this kind, one asks a question and then designs a procedure to answer it. What question, specifically, are you asking?
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
