“Physical” in Science
In the realm of science, particularly in physics, ‘physical’ pertains to the study of matter, energy, and the interaction between the two. It covers everything from the fundamental particles in our universe to the behaviour of galaxies. In physical chemistry, it explores the understanding of the physical properties of molecules, the forces acting upon them, and how they act.
“Physical” in Medicine and Health
In medicine and health sciences, the “physical” pertains more to the human body. When we talk about physical health, we refer to the state of our body, including its structure and function.

A physical exam or physical assessment refers to a general examination conducted by a healthcare provider to check the overall health status of a patient.
