 # Animation timing
 
-Animation timing easing curves create smooth and consistent motion. Easing curves allow elements to
-move between positions or states. These easing curves affect an object's speed, opacity, and scale.
-These animation curves allow acceleration and deceleration changes to be smooth across the duration
-of an animation so that movement doesn't appear mechanical.
+Like color and typography, motion can play a role in defining your app's style and brand. The
+animation timing component provides implementations of the Material Motion easing curve types for
+iOS.
