Bosons and Exchange Particles

Question 1

what are the three types of fundamental particles

Answer 1

fundamental bosons
quarks
leptons

Question 2

what are the 4 fundamental forces

Answer 2

electromagnetic force
gravity
strong nuclear force
weak nuclear force

Question 3

what is a fundamental force

Answer 3

a basic interaction in nature that cannot be broken down into more fundamental processes

Question 4

what is electromagnetic force

Answer 4

a force that gives right to both electrical and magnetic effects

Question 5

when is gravity experienced

Answer 5

between two or more objects that have mass

Question 6

what type of force is gravity

Answer 6

attractive but not repulsive

Question 7

what factor means there is a bigger gravitational force

Answer 7

bigger mass

Question 8

at a particle level which force is stronger gravity or electromagnetic

Answer 8

electromagnetic

Question 9

why is gravity extremely weak at particle level

Answer 9

as particles have very little mass

Question 10

what is strong nuclear force

Answer 10

keeps nuclei stable by counteracting the electrostatic force
of repulsion between protons in the nucleus (as they have the same charge)

Question 11

what is the strongest fundamental force

Answer 11

strong nuclear force

Question 12

what range is the strong nuclear force attractive

Answer 12

less than 3 Fm and above 0.5 fm

Question 13

what is a Fm

Answer 13

1 x 10^-15

Question 14

when is the strong nuclear force repulsive

Answer 14

less than 0.5 fm

Question 15

what does the range diagram look like for strong nuclear force

Answer 15

x-axis = range
y-axis = force
crosses at 0.5
looks like a V

Question 16

what happens when nuclei get too big

Answer 16

they give up particles to reduce the size of the nucleus in a process called radiation

Question 17

what is the weak nuclear force responsible for

Answer 17

beta radiation

Question 18

what are exchange particles

Answer 18

particles that carry force between other particles

Question 19

what is the exchange particle for weak nuclear force

Answer 19

fundamental boson
W boson (plus and minus)

Question 20

what is the exchange particle for the electromagnetic force

Answer 20

virtual photon
fundamental boson

Question 21

what is the symbol for the virtual photon

Answer 21

gamma

Question 22

what is the exchange particle for the strong nuclear force

Answer 22

pions

Question 23

what aren’t pions

Answer 23

fundamental particles

Question 24

why arent pions fundamental particles

Answer 24

as they can be split into a quark and anti-quark pair

Question 25

what is the symbol of a pion

Answer 25

pi
