7C.3 Particles And Forces Flashcards
what are baryons
a particles made is a combination of 3 quarks
what is a proton made up from
2 u and 1 down
what is a neutrons made up from
2 d and 1 u
baryons who decay through strong nuclear force are
highly unstable and have short lives
baryons who decay through weak nuclear force are
they have a longer live (stable)
an anti proton is made up from
3 anti quarks of the quarks in protons making in an anti-baryon
what is an anti-baryon
anti quarks that make up a particles like anti proton
what is a mason
a particles made up from a combination of a quark and a anti quark
what is a pion
a meson created from any up and down quark/anti quark pairings
what is a kaon
a meson created from any combination of up and down quark/anti quark and a strange/anti strange quark
what is the J particle
a meson that is made up from a charm quark and its anti quark so it has no charge
what are the different pions and different kaons

what is a hadron
a particle which can interact via the strong nuclear force
what is a exchange boson
a particle that enables the transfer of force, each of the 4 fundamental particles have their own exchange bosons
what are the 4 forces of nature
- gravity
- electromagnetic force
- weak nuclear force
- strong force
