SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill solves the common issue of motion that feels robotic, stiff, or cheap by providing a tech-agnostic framework for timing, easing, and physical believability.

Core Features & Use Cases

  • Physics-Based Motion: Provides concrete cubic-bezier curves and spring configurations for natural movement.
  • Timing & Rhythm: Offers guidance on duration scaling and stagger math to ensure motion feels weighted and intentional.
  • Use Case: If an animation feels robotic, use this skill to diagnose the easing curve and apply a snappy ease-out or overshoot to make the movement feel premium and responsive.

Quick Start

Use the animation-principles skill to suggest a cubic-bezier curve and duration for a hero element transition that feels snappy and premium.

Frequently Asked Questions about animation-principles

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fix robotic or stiff animation transitions in my UI?

Apply snappy ease-out curves or overshoot spring configurations to diagnose and correct stiff animation. This approach eliminates cheap movement by providing natural weight, premium feel, and responsive rhythm.

What is the best way to define duration scaling for motion design sequences?

The best way to define duration scaling is to calculate timing based on element size and distance. This ensures physical believability and intentional rhythm across video sequences and programmatic motion design tasks.

Does this physics-based motion framework work with any tech stack?

Yes, this physics-based motion framework is tech-agnostic. It provides concrete spring configurations and cubic-bezier curves that you can apply to UI transitions, video sequences, and programmatic motion across any platform.

How do I configure spring physics for a snappy hero element transition?

Configure spring physics for a hero element by applying suggested cubic-bezier curves and duration scaling. This creates a snappy, premium transition that feels weighted and intentional rather than cheap or stiff.

Why does my easing curve make UI movement feel cheap instead of premium?

Your easing curve makes UI movement feel cheap when it lacks physics-based timing and weight. Applying stagger math and precise ease-out configurations diagnoses the issue and restores natural, premium responsiveness.

When should I use stagger math instead of basic easing for motion design?

Use stagger math instead of basic easing when sequencing multiple UI elements or video transitions. Stagger math ensures motion feels weighted and intentional, providing natural rhythm that basic easing cannot achieve.
