Drag: A slider that can be used to reduce the distance the object or objects travel
away from the repelling object.

Rotational Drag
Similar to the Drag behavior, except that it affects Rotation instead of position.
Rotational Drag simulates friction affecting objects that are spinning due to keyframed
or behavior-driven changes to the Rotation parameter. By setting higher Drag values,
you can slow rotational changes to an eventual stop.
Dashboard control
The Dashboard lets you control the Amount of drag. When applied to a layer or group
(such as particles text, or the replicator), the Affect Objects checkbox also appears in
the Dashboard.
Parameters in the Inspector
Affect Objects: This parameter appears when this behavior is applied to an object that
contains multiple objects, such as a layer, particle emitter, replicator, or text object.
When this checkbox is turned on, all objects within the parent object are affected
individually. When this checkbox is turned off, all objects within the layer are affected
by the behavior together, as if they were a single object.
Amount: A slider that can be used to slow down an objects rotation over time,
causing it to eventually come to a stop. Higher Amount values result in the rotation
ending sooner.
Related behaviors
Drag
Spring
The Spring behavior creates a relationship between two objects, so that an object with
the Spring behavior applied to it moves back and forth around a second object. The
Attract To parameter defines the object that serves as the target and center of the
Spring behavior. Additional parameters let you adjust the speed of the behavior (Spring
Tension) and the acceleration of the object at each change in direction (Relaxed
Length).
