Part of the reason is the fact that relatively few high school science teachers, let alone counselors and administrators, have had significant training in physics or are fully aware of its significance to career possibilities. Individuals who are well qualified to teach physics are often attracted away from teaching by the significantly higher paychecks available in industry. Most modern technology came from physics. Any technology involving electricity, magnetism, mechanics, heat, light, sound, optics, etc. comes from physics. Even though the basic knowledge required to discover fertilizers, drugs, plastics, and chemicals comes from chemistry and in some cases biology, all of these items have to be manufactured, and manufacturing is dominated by physics-based technology.
Most branches of sciences contain principles obtained from physics.
Like technology, it is hard to find a branch of science which does not contain some physics-related aspect such as electricity, magnetism, mechanics, heat, light, sound, optics, etc. Chemistry in particular becomes indistinguishable from physics when delving into the atomic model. Physics has been called the most basic science and in many cases it is required in order to understand concepts in other sciences. Physics classes provide practice in both algebra and geometry. However, physics is not a math class.
