SUMMARY

The discussion centers on measuring the acceleration due to gravity (g) using a mass-spring system. Participants clarify that while the period of oscillation (T) of a mass on a spring is given by the formula T = 2π√(m/k), it does not depend on g. However, they establish that g can be calculated using the static deflection of the spring (ℓ) when a mass is applied, leading to the formula g = ℓ(2π/T)². The conversation highlights the importance of distinguishing between static and dynamic measurements in this context.

PREREQUISITES
  • Understanding of Hooke's Law and spring constants
  • Familiarity with simple harmonic motion (SHM) principles
  • Knowledge of basic differential equations
  • Ability to perform measurements of mass and spring deflection
NEXT STEPS
  • Research Hooke's Law and its applications in measuring forces
  • Study the principles of simple harmonic motion (SHM) in detail
  • Learn how to accurately measure the period of oscillation of a mass-spring system
  • Explore methods for calculating gravitational acceleration using static measurements
USEFUL FOR

Students in physics, educators teaching mechanics, and hobbyists interested in experimental physics will benefit from this discussion on measuring gravity with a mass-spring system.

cheers lpfr i already have and its doing great.
i do need my table of mass against extension as I am trying repeating with a range of mass so the extension and period change with the mass and i need to know what the extension is with a certain mass.
but that's awesome cheers.
