 				Moves the body based on [member velocity]. If the body collides with another, it will slide along the other body (by default only on floor) rather than stop immediately. If the other body is a [CharacterBody2D] or [RigidBody2D], it will also be affected by the motion of the other body. You can use this to make moving and rotating platforms, or to make nodes push other nodes.
+				This method should be used in [method Node._physics_process] (or in a method called by [method Node._physics_process]), as it uses the physics step's [code]delta[/code] value automatically in calculations. Otherwise, the simulation will run at an incorrect speed.
 				Modifies [member velocity] if a slide collision occurred. To get the latest collision call [method get_last_slide_collision], for detailed information about collisions that occurred, use [method get_slide_collision].
 				When the body touches a moving platform, the platform's velocity is automatically added to the body motion. If a collision occurs due to the platform's motion, it will always be first in the slide collisions.
 				The general behavior and available properties change according to the [member motion_mode].
