The *Force* field is the simplest of the fields. It gives a constant force towards (positive strength) or away from (negative strength) the object's center. Newtonian particles are attracted to a field with negative strength, and are blown away from a field with positive strength. .. figure:: /images/physics_force-fields_types_force_panel.png UI for a Force force field. For :doc:`Boids Particles ` a field with positive strength can be used as a *Goal*, a field with negative strength can be used as *Predator*. Whether *Boids* seek or fly goals/predators depends on the *Physics* settings of the Boids. Example ======= .. vimeo:: 173807488
