Unit Definitions
What is a Mile per Hour (mph)?
A mile per hour (mph) is a unit of speed commonly used in the United States and the United Kingdom to measure the rate of travel over land.
History
The mile itself has a long history, dating back to ancient Roman times. The mph unit became widely used during the early 20th century with the advent of motor vehicle travel.
Current Use
Today, mph is primarily used in road signs, speed limits, and vehicle speedometers in countries that do not use the metric system.
What is a Speed of Light (c)?
The speed of light (c) is the ultimate speed limit of the universe, defined as approximately 299,792,458 meters per second in a vacuum.
History
The concept of the speed of light has been studied for centuries, with significant advancements made during the 19th century. Albert Einstein's theory of relativity further established light speed as a constant.
Current Use
In modern physics, c is crucial for equations and theories, particularly in relativity and quantum mechanics, serving as a fundamental constant.
