Angular Frequency and Period (ω = 2π/T = 2πν)

ω = 2π/T = 2πν

What each symbol means

SymbolWhat it stands for
TTime period — time for one complete oscillation (s)
νFrequency — number of oscillations per second (Hz = s⁻¹)
ωAngular frequency (rad/s)

When to use this

Fundamental relations connecting ω, T, and ν. T = 1/ν. In SHM, T and ν depend on system parameters (spring constant, length, etc.) but NOT on amplitude. This is a hallmark of SHM. NCERT Eq. 13.7.
