The difference between fast and slow neutrons is in the amount of energy they possess. Fast neutrons tend to "blow through" the nucleus of some isotopes. This causes a disruption but, because they don't stay around, the nucleus restabilizes. Slow, or thermal, neutrons, however, may get absorbed by the same nucleus, which then destabilizes, causing fission.
It should be pointed out that nuclei of different isotopes are affected differently by neutrons. 238U is caused to divide more frequently by a faster neutron, while 235U is caused to divide more frequently by thermal (slower) neutrons, and 233U is caused to divide more or less equally by any.
Fast neutrons have higher kinetic energy and move at higher speeds, making them more likely to cause fission reactions in nuclear reactors. Slow neutrons have lower kinetic energy and are more efficient at causing fission in certain types of nuclear fuel, such as uranium-235. The distinction between fast and slow neutrons is important in nuclear reactions and reactor design.
a moderator would slow the neutrons, hindering breeding
Fast frequency hopping spread spectrum (FHSS) systems switch between frequencies rapidly, usually several times per second, to avoid interference and jamming. Slow FHSS systems switch between frequencies less frequently, providing a more predictable and stable connection but potentially making them more vulnerable to interference.
A moderator in a nuclear reactor slows down fast-moving neutrons to increase the likelihood of fission reactions. By reducing the speed of neutrons, the moderator helps maintain a chain reaction within the reactor core. This process helps control the nuclear reaction and sustain the reactor's power output.
Uranium 238 is considered a slow neutron absorber because it does not readily absorb fast neutrons. It can capture slow neutrons and transform into plutonium 239 through a nuclear reaction called neutron capture.
Graphite is used as a moderator in nuclear reactors to slow down neutrons produced during nuclear fission. Slower neutrons are more likely to cause additional fission reactions, allowing for a sustained nuclear reaction. Graphite is also used as a structural material in some reactor designs.

slow is when the gravity pushes u down and fast is when u run

One is thrown slow and the other is thrown fast.
in reacter U-235 fission is due to slow neutrons because in reacter the probability of fission from fast neutron is approximatly zero.
Slow succession happens slow and Succession happens very fast. Simple!
Yes, in fact for a sustainable nuclear chain reaction to work, you have to slow neutrons down.
In a business presentation the points of interest change through the presentation. How fast the screen presentation changes depends on whether you use fast fade between slides or slow fade
No, moderation of neutrons is not always used to slow nuclear fission. In some types of nuclear reactors, such as fast breeder reactors, fast neutrons are intentionally not moderated to slow down the fission process. These reactors operate using fast neutrons to sustain a chain reaction. However, in most commercial nuclear reactors, moderation of neutrons is employed to slow down the fission process and maintain a controlled chain reaction.
a fish is fast and breathes in water and a turtel is slow and green
With a fast metabolism you burn fat faster and with a slow metabolism you burn fat slower. It's good to have a fast one because you don't have to watch what you eat as much.
