		<method name="add_constant_central_force">
			<return type="void" />
			<param index="0" name="force" type="Vector2" default="Vector2(0, 0)" />
			<description>
				Adds a constant directional force without affecting rotation that keeps being applied over time until cleared with [code]constant_force = Vector2(0, 0)[/code].
				This is equivalent to using [method add_constant_force] at the body's center of mass.
			</description>
		</method>
		<method name="add_constant_force">
			<return type="void" />
			<param index="0" name="force" type="Vector2" />
			<param index="1" name="position" type="Vector2" default="Vector2(0, 0)" />
			<description>
				Adds a constant positioned force to the body that keeps being applied over time until cleared with [code]constant_force = Vector2(0, 0)[/code].
				[param position] is the offset from the body origin in global coordinates.
			</description>
		</method>
		<method name="add_constant_torque">
			<return type="void" />
			<param index="0" name="torque" type="float" />
			<description>
				Adds a constant rotational force without affecting position that keeps being applied over time until cleared with [code]constant_torque = 0[/code].

		</method>
		<method name="apply_central_force">
			<return type="void" />
			<param index="0" name="force" type="Vector2" default="Vector2(0, 0)" />
			<description>
				Applies a directional force without affecting rotation. A force is time dependent and meant to be applied every physics update.
				This is equivalent to using [method apply_force] at the body's center of mass.
			</description>
		</method>
		<method name="apply_central_impulse">
			<return type="void" />
			<param index="0" name="impulse" type="Vector2" />
			<description>
				Applies a directional impulse without affecting rotation.
				An impulse is time-independent! Applying an impulse every frame would result in a framerate-dependent force. For this reason, it should only be used when simulating one-time impacts (use the "_force" functions otherwise).
				This is equivalent to using [method apply_impulse] at the body's center of mass.

			<description>
				Applies a positioned force to the body. A force is time dependent and meant to be applied every physics update.

			<return type="void" />
			<param index="0" name="impulse" type="Vector2" />
			<param index="1" name="position" type="Vector2" default="Vector2(0, 0)" />
			<description>
				Applies a positioned impulse to the body.
				An impulse is time-independent! Applying an impulse every frame would result in a framerate-dependent force. For this reason, it should only be used when simulating one-time impacts (use the "_force" functions otherwise).

		<method name="apply_torque">
			<return type="void" />
			<param index="0" name="torque" type="float" />
			<description>
				Applies a rotational force without affecting position. A force is time dependent and meant to be applied every physics update.
				[b]Note:[/b] [member inverse_inertia] is required for this to work. To have [member inverse_inertia], an active [CollisionShape2D] must be a child of the node, or you can manually set [member inverse_inertia].
