Foot/second
The foot per second (ft/s) is a unit of speed commonly used in the United States to measure the velocity of objects, particularly in engineering and physics. It indicates how many feet are covered in one second and is often used in contexts such as projectile motion or fluid flow.
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.
