Damping Controls the degree to which orbital particle motion is restrained
per frame. Smaller values produce a wide spiral, while larger values produce
a thin spiral. Default=5.0. Range=0 to 100.
Radial Pull Specifies the distance from the drop axis at which the particles
rotate.
Range The distance from the center of the Vortex icon, in system units, at
which Radial Damping has its full effect. Takes effect only when Unlimited
Range is turned off.
Falloff Specifies the distance beyond the Radial Range within which Radial
Damping is applied. Radial Damping is strongest at the Range distance,
decreases linearly out to the limit of the Radial Falloff, and has no effect beyond
that. Takes effect only when Unlimited Range is turned off.
Damping Controls the degree to which Radial Pull is restrained per frame.
Default=5.0. Range=0 to 100.
CW/CCW Determines whether particles rotate clockwise or counterclockwise.

Icon Size Specifies the size of the icon.

The Drag space warp is a particle motion damper that reduces particle velocity
by a specified amount within a specified range. The damping can be applied
linearly, spherically, or cylindrically. Drag is useful for simulating wind
resistance, transfers into dense media (like water), impacts with force fields,
and other, similar situations.
With each damping type, you can control the damping effect along several
vectors. The damping is also affected by particle system settings, such as speed.
NOTE To create a uniform drag effect, the default value for all directional
parameters is 5.0%.
