...or gravity free fall is as a current/flow multiplication phenomenon.
As an electronic avalanche,when the free electrons are accelerated by the electric field to very high speeds,the avalanche can result in the flow of very large currents.
If we pair the flow of electrons with a flow of holes,we get a continuous process.
In avalanche transistors and avalanche photodiodes,this effect is used to multiply tiny currents,thus increasing the gain of the devices.
You can think more about pulse circuits...
If we transpose this operation from an electric field to a gravitational field,we need a little bit of imagination...
Remind that a quality of the imagination is to flow and not to freeze..but this time the gravity flows and matter is the "freezer".

......can be considered in two well-marked,recognizable each to each motions.
The first one is alike a common pendular fall in the gravitational field:it's the opening ,primary avalanche...on the vertical line.
We can discern,figure out that some potential thrust,push,energy due to the rotational inertia remains "hidden","frozen" in the pivot/fulcrum.
The second power of movement,that we can set free,is just this one: mass-slide on the radius due to the same rotational inertia,a kind of next avalanche...on the turning line.
A real mass avalanche consists in an amassing,agglomerating and sliding process in the same time.
We can replace the aggrandizement of mass with a similar "expansion",augmentation of the long arm-short arm pair difference(as seen from the rotation axis point of view): for this,we must link together,inside the fulcrum the both arms.
So,in two words,we must release the free fall on the vertical line and the radii lines,to size,get in our hands a full avalanche wonderful thing,phenomenon: a twin fall,in two frames,gravity and inertia.
Every generous illusion,mirage seems at first impossible...but fortune knocks at every man's door ,once in a life,if you can see it at a quickly glance.
