# What is Spring?

Motion driven by physics (tension, mass, damping) instead of a fixed duration. Springs handle interruptions naturally and feel more alive than timed easing curves.

## In real work

Animate the card dismiss with a spring. Stiffness 300, damping 30. It should feel physical when the user releases it.
