electric field 
a region of space around a charge where another charge will experience a force
voltage 
the energy given to each coulomb of charge
magnetic field 
a region of space around a magnet where another magnet will experience a force
the standard model 
a model for classifying fundamental particles and their interactions
fundamental particle 
a particle that is not made up from any other particles, it is in its simplest form
composite particle 
a particle that is made up of other particle
gravitational force 
the force of attraction between objects with mass
radioactive decay 
when an unstable nucleus will try to become more stable by emitting an alpha particle, beta particle or gamma ray
nuclear fission 
the process in which an unstable, heavy atomic nucleus splits into two or more lighter nuclei (called fission fragments) with energy being released
nuclear fusion 
the process of small nuclei joining together to form a larger nucleus, with energy being released
irradiance 
the power per unit area of electromagnetic radiation incident on a surface
point source 
a small compact source that emits radiation uniformly in all directions
