How to Choose a Physics Research Topic

Choose a physics research topic by asking four questions:

1. Is the topic clear?
   Avoid topics that are too broad, such as “quantum physics.” A better topic is “how quantum tunneling is used in modern electronics.”
2. Can you find reliable sources?
   A strong topic should have books, academic papers, university pages, or scientific articles available.
3. Is the topic suitable for your level?
   High school students may choose friction, light, electricity, or motion. College students can choose quantum mechanics, thermodynamics, nuclear physics, or astrophysics.
4. Can you explain the topic with evidence?
   A good physics paper should include definitions, laws, examples, formulas when needed, and real applications.

How to Narrow a Physics Topic

A broad topic becomes stronger when it is turned into a focused research question.

Broad Topic	Better Research Question
Gravity	How does gravity affect the motion of planets?
Light	How does lens shape affect image formation?
Electricity	How does wire length affect electrical resistance?
Heat	Which insulation material reduces heat loss most effectively?
Sound	How does temperature affect the speed of sound in air?
Quantum physics	How does quantum tunneling help explain modern electronic devices?
Renewable energy	How does light intensity affect solar panel efficiency?
