Nuclear Physics is a field of physics, yes. It involves interactions between atomic nuclei. Nuclear fission, nuclear fusion, nuclear decay (though in some ways that is more particle physics).
Atom has got a hard material packed at its centre, called nucleus. Its dimension is some 10,000 times smaller than that of the atom itself. If the branch of physics, deals with the nucleus and its...
Gravitational Field - An area that surrounds an object, within which it will exert a gravitational force on any other object. Electric Fields, Magnetic Fields.
There are two main fields of physics. They are: Applied physics-Engineering and stuff like that including other branches like astrophysics (physics in astronomy) and particle physics (study of...
Yes, there is. Nuclear chemists are those chemists with "extra" physics knowledge and an interest and a willingness to work with radioactive materials. Much of their work is in radiation biology, as...
