ONE FORMULA, ONE ANSWER
Mass Spring Natural Frequency Calculator
Check the undamped natural frequency of a linear vibration model. Choose input units and calculate one value within the stated conditions.
Inputs
Calculations run in this browser. Scientific notation such as 1.2e-3 is supported. Do not group thousands.
Result
Undamped natural frequency f_n
Enter values and select Calculate.
f_n = √(k/m) / (2π)
Assumptions
Use k,m>0. Assume one linear degree of freedom and negligible spring mass. Damped natural frequency and forced vibration response are not calculated.
Displayed values are floating-point approximations. Measurement uncertainty and design safety factors are not calculated.
