The weak nuclear force is one of the four fundamental forces of nature (the other 3 being the strong nuclear force, the electromagnetic force and gravity)


The Weak Force exerts its influence on all particles. It is responsible for beta radiation and plays an important role in nuclear reactions such as fusion. It acts over a very short range #(10^-18fm)#.

The exchange particle responsible for transmitting the weak force is the Boson (W+ and W-). These are relatively massive which means a short lifetime and therefore distance.

The weak force can alter the flavour of a quark. Hence strangeness is not conserved in weak interactions.
