Centripetal force is defined as, "the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation," while centrifugal force is defined as "the apparent force that is felt by an object moving in a curved path that acts outwardly away from the center of rotation," according to Merriam Webster Dictionary.
-- Free neutrons collide with Uranium nuclei.
If one is absorbed, then
-- the Uranium nucleus falls apart,
producing
-- smaller nuclei,
-- energy,
and
-- more free neutrons.
