Basic methods of physics research
The basic methods of physics research are as follows:

1. observation method: This is the most basic research method, which collects data by directly observing and measuring physical phenomena. For example, observe the movement of stars with a telescope and observe microscopic particles with a microscope.

2. Experimental methods: Design experiments to verify the theory or discover new physical phenomena. Experiments can be qualitative (such as measuring the mass and length of an object) or quantitative (such as measuring current and voltage). Experiments can be divided into laboratory experiments, field experiments and simulation experiments.

3. Mathematical modeling: describe and predict physical phenomena by establishing mathematical models. This includes determining the relationship between physical quantities (such as Newton's law of motion) and solving complex equations (such as Schrodinger equation). Mathematical modeling can help researchers better understand physical phenomena and provide theoretical basis for experiments.

4. Computer simulation: numerical simulation of physical phenomena with computer programs. This method can deal with a large number of data, improve the calculation efficiency, and avoid possible dangers and uncontrollable factors in the experiment.

5. Theoretical analysis: By analyzing known physical laws and theories, we can draw new conclusions or predict future physical phenomena. Theoretical analysis can help researchers deeply explore physical problems and discover new physical laws.

6. Comprehensive method: A variety of research methods are combined with each other to solve complex physical problems. For example, experimental data can be combined with mathematical models to verify the accuracy of theoretical prediction; Or combine theoretical research with computer simulation to explore new physical phenomena.

In a word, there are various research methods in physics, and researchers need to choose the appropriate method according to specific problems and goals. In practical application, it is usually necessary to use various methods to improve the quality and effect of research.

Physics is a subject that studies the most common laws of motion and the basic structure of matter. Physics, as the leading discipline of natural science, studies the most basic motion forms and laws of all substances from the universe to elementary particles, so it has become the research basis of other natural science disciplines.
