I've been reading about this but I couldn't find a conclusive answer.
I have to measure the spring constant (k) using a vertical spring-mass (M) configuration and using two different methods:
- static method: I calculate elongation vs weight and find a linear fit of the data (the slope is K)
- dynamic method: I measure the period and calculate K using K=w2*m
I don't know what mass i need to use to calculate K.
In the static measure, the weight i consider is: w = (springmass/2 + M)*g
In the dynamic method I am supposed to use: m = M + (springmass)/3
Am I missing something? I don't fully understand the static measure correction of the mass.
sorry for my english and for the format (first post)
Thanks!
