Natural Frequency Calculator

Find the natural frequency of a spring-mass system.

Natural frequency (Hz) 7.958
Angular frequency (rad/s) 50

Formula: f = (1 ÷ 2π)·√(k ÷ m)

Step-by-step with your numbers:
1. Values used:
2. Stiffness = 5,000 N/m
3. Mass = 2
4.
5. Natural frequency = 7.958Hz
6. Angular frequency = 50rad/s
Did we solve your problem today?

Every spring-mass system has a natural frequency at which it prefers to oscillate.

The math behind it

f = (1/2π)·√(k/m). Stiffer springs and lighter masses vibrate faster.

Worked example

k = 5000 N/m, m = 2 kg → about 7.96 Hz.

FAQ

Why avoid resonance?

Driving a system at its natural frequency can build up dangerously large vibrations.
