Spring stiffness: formulas and units of measurement

Spring stiffness: symbol k, unit N/m. Formulas and explanations for Mechanics, Oscillations and waves.

k

\frac{\text{N}}{\text{m}}

newton per meter

KEY CONNECTIONS

Formulas

F_{elastic} = k ∣ Δ l ∣

Fupr = k|Δl|

E_{p} = \frac{k ( Δ l ) ^{2}}{2}

Ep = k(Δl)² / 2

T = 2 π \frac{m}{k}

T = 2π√(m / k)

NOTATION

$F_{\text{elastic}}$: Elastic force is a force that occurs when a body deforms.
$k$: The stiffness of a spring is a characteristic of its resistance to deformation.
$\Delta l$: Elongation is a change in the length of a body during deformation.
$E_{\text{p}}$: Potential energy is the energy of the relative position of bodies or parts of a system.
$T$: A period is the time of one complete repetition of a process.
$m$: Mass is a scalar physical quantity that is a measure of the inertia of a body.
