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.
Knot
The knot (kn) is a unit of speed equal to one nautical mile per hour. It is commonly used in maritime and aviation contexts to express the speed of ships and aircraft. The knot is an important unit in navigation, where distances are often measured in nautical miles.
