What is your spring constant?

Explanation / Answer

Assuming that the mass is suspended vertically, the only two forces acting are the downward force W=mg and the restoring force from the spring given by: |F| = kx

so, for equilibrium, mg = kx

=> k = F/x

where Force F = mg

take g = 9.8 m/s2.

from the data above, this gives the spring's constant to be approximately k = 4.9 N/m. Plot mg vs displacement x to get the linear plot. The slope of this graph will give the spring's constant k.
