Spring · The feel of a bounce
Spring弹簧
- physical
- natural
- interruptible
Motion described by stiffness and damping, as if a spring were pulling the element. It handles a change of direction mid-flight naturally.
When to use it
Use it when the user can interrupt the element or it must follow a finger; for a simple one-off fade, “Ease-out” is less work.
Parameters
stiffness 300 · damping 30 · mass 1 (settles in ~350ms)
Recipe
Spring → 350msSpring → stiffness 300 · damping 30 · mass 1 (settles in ~350ms)
One sentence for your AI
Change this panel's expansion to a spring: stiffness 300, damping 30, mass 1, so it settles naturally and can be interrupted.
