Natural vibrations

Periodic vibrations with no external force and no resistance. Amplitude and frequency stay constant forever, and no energy is lost — a state only truly possible in vacuum.

Formulas

ω = √(k/m)ω = 4.47 rad/s

Angular natural frequency — set only by the spring and the mass.

T = 2π√(m/k)T = 1.40 s

Natural time period: heavier mass or softer spring means slower vibration.

f = 1/Tf₀ = 0.71 Hz

Natural frequency in hertz — vibrations completed each second.
