Fundamental forces

Question 1

Four types of fundamental forces

Answer 1

Strong interactions, weak interactions, electromagnetism and gravity

Question 2

How do these forces arise

Answer 2

Due to the exchange of bosons - force mediating particles

Question 3

How do forces exist between fermions?

Answer 3

A fermion will produce a boson, which is then taken up by another fermion

Question 4

Electromagnetism and it’s respective boson

Answer 4

Interactions between particles with electric or magnetic properties.
Boson for electromagnetism is photon

Question 5

Gravity and its respective boson

Answer 5

Interactions between objects of mass.

Boson for gravity is graviton

Question 6

Strong interaction and it’s respective boson

Answer 6

Interactions between hadrons in the nucleus and the quarks within the hadrons.
Boson for strong interactions is gluon

Question 7

Weak interaction and it’s respective boson

Answer 7

Beta decay in the nucleus

Boson for weak interaction is W and Z bosons

Question 8

Laws of conservation for these forces

Answer 8

All of the forces obey the conservation laws for energy, angular momentum and charge.
