Follow-up of this question How would I be able to control the falloff of a node setup like this?
I want to be able to control the falloff of a thing like this. how would I be able to do this? Thanks!

To obtain a falloff, you need some function of
distance from Falloff Center, which is
1 when the distance is
0 when the distance is
Falloff Radius. A Map Range node can do this for you, and clamp its output to 0 for anything beyond the radius.
0 -> Falloff Radiusis mapped to
1 -> 0
The effect that's being faded, here, is the movement of vertices away from the Empty (i.e. movement along
e->p). Now we have a 0 -> 1 falloff, we can multiply that vector by a scale of the falloff, and add it to the position...
Falloff is also raised to a power, to provide some option in falloff's curve. You could get more control by using an Attribute Curve Map node instead of the Power, but I haven't found a way to present that curve to the user in the GN modifier.
This gif shows change in Radius.
This one, Power, and Scale.
