The four fundamental interactions 2.3.1

Question 1

Name the four fundamental forces from strongest to weakest

Answer 1

-strong
-electromagnetism
-weak
-gravity

Question 2

what does gravitational interaction only affect

Answer 2

particles with mass

Question 3

what does electromagnetic interaction only affect

Answer 3

particles with charge

Question 4

what particles does weak interaction affect

Answer 4

all particles

Question 5

what does strong interaction affect

Answer 5

all hadrons

Question 6

what is an exchange particle?

Answer 6

-cause particles to exert forces of eachother by transferring energy and momentum
-When two particles exert a force on each other, a virtual particle is created

Question 7

how long do virtual particles exist for

Answer 7

a short amount of time and carry the fundamental force between each particle

Question 8

name the exchange particle of strong interaction

Answer 8

pions (between nucleons) gluon (between quarks)

Question 9

name the exchange particle of weak interaction

Answer 9

w+, w-, Z0

Question 10

name the exchange particle of electromagnetic interaction

Answer 10

photons
