About Speed

Definition: The speed of light in vacuum (symbol: c) is exactly 299,792,458 meters per second, a fundamental physical constant.

History: Measured increasingly accurately since 1676. Defined as exact value in 1983, now used to define the meter.

Current Use: Fundamental constant in physics, relativity theory, telecommunications, and scientific calculations.

Examples: Electromagnetic radiation, particle physics calculations, GPS timing corrections, optical communications

About Meter

Definition: The meter per second (symbol: m/s) is the SI unit of speed, expressing distance traveled in meters during one second.

History: Natural derivative of the meter and second SI base units. Became standard for scientific velocity and speed measurements.

Current Use: Universal standard for scientific speed measurements, physics calculations, and engineering applications worldwide.

Examples: Walking: 1.4 m/s, running: 5-10 m/s, cycling: 5-15 m/s, sound in air: 343 m/s
