Make Your Text React to Collisions in After Effects (Newton + Expressions Tutorial)

In this tutorial, you'll learn how to create a fully physics-driven kinetic typography animation using After Effects, the Newton plugin, and a single powerful expression. We’ll use Newton’s Export Contacts feature to detect collisions and trigger a list of short, expressive words — everything from “Weeee” to “Ouch”, “Yikes” or “Thud” — changing in real time as objects hit walls or each other.
