The force that drains energy from a spring animation, controlling how quickly oscillation dies down and the element comes to rest.
Example Usage
Increase the damping. The card shouldn’t wobble three times before it settles.
ζ 0.19 · crosses rest 5× / drag to add friction
Fig 1.3 Damping
Damping is the taste parameter of spring motion. Low damping is
bouncy and toy-like; critical damping settles with no oscillation at all and
reads as calm confidence. Most product UI wants to live just below critical:
one subtle overshoot, then rest.
