I. E. Is a part of natural philosophy and a natural science that involves the study of matter[6] and its motion through space and time, along with related concepts such as energy and force. [7] More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. [8][9][10] Physics is the field of science that studies the physical world. From the large (galaxies, planets, etc) to the small (how proteins fold, atoms, etc) physics plays a role.
It is a trial science that studies the properties of matter, motion, force, energy, space and time. Physics has a number of divisions or sub-categories. Each of these are more focused areas of study. Quantum Physics, the study of the quantum world (smaller than an atom). Particle Physics, the study of atomic and quantum particles such as electrons, protons, gluon’s and neutrinos. Thematic Physics, this is the branch of physics which deals in theory. It’s generally at the forefront of physics and thought. After a theory has been shown possible that theory may move into another ranch of physics.
Astrophysics, studies aspects of stars, galaxies and space. It is closely linked with astronomy. Medical Physics, the study of physics and it’s role in medicine. For example, radiation therapy, the development of certain medicines and areas of neurology all require a deep understanding of physics. Geophysics, the study of physics as it relates to Earth. Mathematical physics, General ; Special Relativity, Classical Mechanics, Thermodynamics, Electromagnetism and Temporal Mechanics are all other divisions of physics.
Physics is a branch of science that deals with mater and motion; it also focused on the “Fundamental Laws of the Universe. ” Two Main Branches 1. Pure Physics 2. Applied Physics Pure Physics 1. Mechanics – study of forces ; energy on bodies of fluids at rest or in motion. 2. Optics – study of not only light, but also the electromagnetic spectrum Just above x-rays to Just below microwaves. 3. Thermodynamics – study of heat in terms of molecular motion. 4. Quantum Physics – study based on the theory of electromagnetic wave (matter interaction. 5.
Plasma – study of the 4th state of eater, unionized particles ; their properties. 6. Electromagnetism Physics – the study of matter, energy and their interactions – is an international enterprise, which plays a key role in the future progress of humankind. The support of physics education and research in all countries is important because: 1. Physics is an exciting intellectual adventure that inspires young people and expands the frontiers of our knowledge about Nature. 2. Physics generates fundamental knowledge needed for the future technological advances that will continue to drive he economic engines of the world. . Physics contributes to the technological infrastructure and provides trained personnel needed to take advantage of scientific advances and discoveries. 4. Physics is an important element in the education of chemists, engineers and computer scientists, as well as practitioners of the other physical and biomedical sciences. 5. Physics extends and enhances our biological, and environmental sciences, plus astrophysics and cosmology – subjects of substantial importance to all peoples of the world.
Physics improves our quality of life by providing the basic understanding necessary for developing new instrumentation and techniques for medical applications, such as computer tomography, magnetic resonance imaging, positron emission tomography, ultrasonic imaging, and laser surgery. 1. Engineering – harnessing of materials, forces ; energy so they can be of use to man 2. Optometry – knowledge of optics as applied to vision instruments Fallacy, keeping the body in motion by performing physical activities that you find enjoyable is the best way to implement fitness in one’s life.
For example, riding a bike, taking a brisk walk, roller balding and dancing are fun ways to experience exercise. Exercise is only beneficial when it is strenuous. Fallacy, extreme exercise is unnecessary to experience the benefits of a fitness program. Excessive exercise runs the gambit of overstraining. For example, a brisk walk of 3. 5 miles per hour on a treadmill will provide health advantages. Allow the body to rest by alternating challenging workout days with easier ones. Each exercise session is only effective if burning is felt in the muscles.
While moderate muscle soreness is to be expected, the old wives tale, “No pain, no gain” is untrue. Exercise should not cause aches, pains or burning sensations. An adequate work-out does not necessitate making muscles burn. When pain is experienced, exercise should be ceased. Aerobic and cardiovascular exercise are the only types of exercises that matter. Fallacy, a well-balanced physical regimen includes the following components: strength, cardiovascular/aerobic and flexibility training. Strength training for women always leads to bulking up.
Since women do not have the testosterone hormone that can builds bulky muscles in men, strength training will enhance muscular tone and strength The formula for six- pack abs is by doing exercises targeted to flatten the stomach. Although, abdominal exercises (sit-ups, crunches), are vital for strengthening muscles and improving posture, excess abdominal fat will not create abs of steel. In the realm of exercise, losing weight in a specific spot of the body is not feasible. Applied Physics
