What are the purposes of research?
Research is simply a detailed and focused study, using scientific methods, to understand why something happens and/or what are its applications. Research is basically done for two purposes: to understand the world around us or why things or process work the way they do and to understand the applications of these processes. In other words, either pure research is carried out or applied research is carried out. Pure research is conducted to determine why/how something works and can be anything (not necessarily related to science), such as how heart works or why we like sugar in our tea? Applied research is dedicated to finding the applications of known processes. Examples can be designing the best mechanical pump based on our heart or finding out how to transport sugar safely in airplanes or spacecrafts so people (or astronauts) can enjoy tea.
Hope this helps.
