The discussion revolves around measuring the gravitational acceleration (g) using a mass attached to a spring. Participants clarify that the period of oscillation for a mass on a spring does not depend on g, as the formula for the period is T = 2π√(m/k), where m is mass and k is the spring constant. A method is suggested to find g by measuring the static deflection of the spring when a mass is applied, using the relationship mg = kx, where x is the extension of the spring. The conversation highlights the confusion between static and dynamic measurements, emphasizing that static deflection can provide a more straightforward approach to determine g. Ultimately, the participants agree that while the method may not yield high precision, it can still provide an approximate value for g.

cheers lpfr i allready 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.
