Experimental physics refers to the branch of physics that focusses on conducting experiments to test scientific hypotheses and theories. Synonyms for experimental physics can include "observational physics," which emphasises the act of observing natural phenomena to gather data, or "laboratory physics," which centres on conducting experiments in a controlled laboratory setting. Other synonyms may include "empirical physics," which refers to the use of empirical observation and measurement to develop scientific theories, or "applied physics," which focuses on the practical application of physics principles in various fields such as engineering, medicine or environmental science. Regardless of the term used, experimental physics remains a crucial component in furthering our understanding of the physical world around us.
