1. What are nuclear forces?
Nuclear forces are the forces that act between nucleons (protons and neutrons) in the nucleus of an atom. These forces are relatively weak compared to other fundamental forces acting between individual atoms. Because, nucleons have a large mass. These forces play a vital role in determining the properties of all nuclei. The properties of these interactions are governed by different parameters such as masses and charges of individual particles.
2. What is the difference between a strong nuclear force and a weak nuclear force?
Strong nuclear force and a weak nuclear force can be differentiated as follows:
Strong nuclear force acts between nucleons (protons and neutrons) within the nucleus only, while the weak nuclear force also acts on protons and neutrons but it can act at a distance of up to 1 meter.
Strong and weak nuclear forces govern the structure of the nucleus.
Strong nuclear force holds the protons and neutrons together within a nucleus, while the weak nuclear force is responsible for a number of phenomena such as beta decay, which occurs when a neutron decays into a proton, electron, and antineutrino.
3. What is a normal nuclear force?
The interaction is called the strong nuclear force, which is a fundamental force that acts between particles inside the nucleus of an atom. This is also sometimes called the 'color force' or simply 'strong'. In quantum chromodynamics (QCD), a theory of quarks and gluons, interactions similar to those involving the strong nuclear force (such as gluon-gluon and quark-quark interactions) are mediated by particles called gluons.
