Q

what is the gravitational force and its boson

A

the weakest of the four fundamental forces, and acts on all object and its exchange boson is graviton

17
Q

what is the electromagnetic force and its boson

A

a force that acts between objects and charges and its exchange boson is the photon

18
Q

what is the week nuclear force and its exchange boson

A

a force that effects all object of matter it acts at small ranges its exchange boson of the W boson or Z boson (occurs in decay)

19
Q

what is a photon

A

a quantum of electromagnetic radiation

20
Q

what happens between protons and electrons

A

in order for them to attract each others opposite forces they pass photons back and fourth to each other
