The Gravity icon appears. For planar gravity (the default), the icon is a
wireframe square with a direction arrow on one side. For spherical gravity,
the icon is a wireframe sphere.
The initial direction of planar gravity is along the negative Z axis of the
construction grid that is active in the viewport where you drag. You can
rotate the gravity object to change the direction.

Strength Increasing Strength increases the effect of gravity; that is, how objects
move in relation to the Gravity icon's direction arrow. Strength less than 0.0
creates negative gravity, which repels particles moving in the same direction
and attracts particles moving in the opposite direction. When Strength is set
to 0.0, the Gravity space warp has no effect.
Decay When Decay is set to 0.0, the Gravity space warp has the same strength
throughout world space. Increasing the Decay value causes gravity strength
to diminish as distance increases from the position of the gravity warp object.
Default=0.0.
Planar Gravity effect is perpendicular to the plane of the Gravity warp object
throughout the scene.
