What jobs do non-physicists hold that use physics everyday? Every job has some relation to physics, but there are some examples that many would not think of as being physics-intensive. Athletes, both professional and amateur, use the principles of physics all the time. The laws of motion affect how balls are batted and thrown, and what happens when athletes tackle, run, and jump. The more an athlete and coach understand and use their knowledge of physics in their sport, the better that athlete will become.
Automobile crashes are subject to the laws of physics, and people who reconstruct crashes use physics concepts such as momentum, friction, and energy in their work. Modern electronics, from televisions and computers to smart telephones and music players, depend on the applications of physics. Telephone and computer networks are connected by fiber optics that use the principles of the refraction of light to transmit the light over thousands of miles.
Modern medical imaging methods, including X rays, CT scans, ultrasound, PET, and magnetic resonance imaging (MRI), all depend on physics. Doctors, health providers, and technicians in hospitals and medical clinics must have an understanding of these methods in order to select the best device and interpret the results.
