Final answer:
Physical agents refer to different forms of energy, such as momentum, rotational motion, and vibrations used in sports science, and gamma-rays, alpha-particles, beta-particles, neutrons, and positrons in medicine, all of which require knowledge of physics to be understood and applied effectively.
Step-by-step explanation:
When we talk about Physical Agents, we are referring to various forms of energy that can have an impact on the physical state of matter. In the context of sports science and health, this often relates to the physics concepts such as momentum, rotational motion, and vibrations. For instance, understanding how momentum affects movement can help in enhancing athletic performance or in injury prevention strategies.
Moreover, in rehabilitation, physical therapists might use their knowledge of physics to understand muscle contraction and the release of energy during exercise. They also need to be aware of the biochemical reactions occurring within the body to make informed decisions about a patient's treatment plan.
Another aspect of physical agents can be found in medicine, for example, the use of nuclear radiations like gamma-rays, alpha-particles, beta-particles, neutrons, and positrons in diagnostics and treatments. Each of these agents interacts with matter in specific ways, which can be understood and manipulated based on principles of physics.
