The study of physics is significant because the concepts serve as the basis for more complicated concepts that apply to geology, chemistry and other sciences. Quite a few of the tools that have come from advances in technology and science have come from the result of the work of physicists.Know More
Medical professionals use nuclear magnetic resonance imaging, X-rays, lasers, synchrotron radiation and electron microscopes, all of which function as a result of the operation of the principles of physics. Without a functioning knowledge of quantum mechanics, building the electronic components that form the working parts of computers would not be possible. Traveling any distance in a quick amount of time, communicating across distances and even carrying out business on a global level requires the assistance of physics.
Other examples of the importance of physics include awareness of the effects of natural events. When tsunamis start to rise and threaten devastation, it is the knowledge of physics that helps scientists know which areas of the world's population to warn and the proper precautions that they must take. The principles of physics that involve planetary movement drive the design and function of manmade satellites. Without a knowledge of the basic principles of motion and force, mankind's existence would still be quite primitive.Learn more about K-12
Pitch, in physics, is equivalent to the frequency of sound waves, which are any compression waves in a medium. The word "pitch" is used specifically in situations where humans are perceiving the frequency of sound and changes in that frequency. Differences and changes in perceived pitch aren't always the same as the actual differences and changes in the frequencies of the sounds perceived.Full Answer >
EMF is the abbreviation for electric and magnetic fields. EMF's are produced by the use of electrical power, and they are a type of radiation that are categorized as ionizing and non-ionizing.Full Answer >
In the study of physics, energy is defined as the capacity to do work. That energy or force is measured in units called joules.Full Answer >
In the theory of relativity in the study of physics, the interval between two events is called proper time. Proper time is based on a clock that measures both events.Full Answer >
