Q: What are research objectives for any application?
The latter part of your question is not very clear. Perhaps you mean research objectives that can be applied or implemented for a particular problem.
Nevertheless, objectives are the specific goals of your research. While your research has an overall purpose, you need to break it down into smaller goals. However, each goal should be specific. Therefore, you should express it very clearly. Also, each objective should be achievable.
You can arrive at objectives by studying about the topic in greater detail, through a comprehensive literature search. The literature search typically uncovers areas and avenues for you to explore as a part of your research.
