noun Physics.
a force between elementary particles that causes certain processes that take place with low probability, as radioactive beta-decay and collisions between neutrinos and other particles.

Weak inter-action force
is always a great word to know.
So is gobo. Does it mean:
| a scrap or morsel of food left at a meal. |
| a screen or mat covered with a dark material for shielding a camera lens from excess light or glare. |

weak force  (wēk) Pronunciation Key
The fundamental force that acts between leptons and is involved in the decay of hadrons. The weak nuclear force is responsible for nuclear beta decay (by changing the flavor of quarks) and for neutrino absorption and emission. It is mediated by the intermediate vector bosons (the W boson and the Z boson), and is weaker than the strong nuclear force and the electromagnetic force but stronger than gravity. Some scientists believe that the weak nuclear force and the electromagnetic force are both aspects of a single force called the electroweak force. Also called weak nuclear force, weak interaction. Compare electromagnetic force. |
