Velocity of Light (in vacuum)
The velocity of light (c) is a constant that represents the speed at which light travels in a vacuum, approximately 299,792,458 meters per second. It is a fundamental constant in physics and is used in various equations, such as Einstein's theory of relativity. This speed is the upper limit for the speed at which information or matter can travel.
Kilometer/second
The kilometer per second (km/s) is a unit of speed that represents how many kilometers an object travels in one second. This unit is often used in astronomy and space science to describe the velocities of celestial bodies and spacecraft, as these speeds are far beyond those encountered in everyday life.
