Matter anything that occupies space and has mass
Mass primary characteristic of matter
Mass is measured in kg
Fundamental complex building blocks of matter atoms and molecules
kilo stands for 1000
(SI) International system
Potential Energy the ability to do work by virtue of position
Kinetic Energy the energy of motion
Chemical Energy is the energy release by a chemical reaction
Electrical Energy work that can be done when an electron moves through electric potential
difference (voltage)
Thermal Energy is the energy of motion at the molecular level
Nuclear energy is the energy that is contained within the nucleus of an atom
Electromagnetic Energy x-rays, gamma radiation, ultraviolet light, infrared, visible light
Radiation energy emitted and transferred through space
Irradiated matter that intercepts radiation and absorbs all or part of it
Ionizing radiation type of radiation that that is capable of removing or orbital electron from the atom
which it interacts
, Radiologic Science for Technologists Bushong Chapter 1 Study Guide
Ionization interaction between radiation and matter where orbital electron is removed
Ion pair orbital electron and the atom from which it was seperated
