ESCAPE VELOCITIES Meaning and
Definition
-
Escape velocity is a term used in physics to define the minimum velocity required for an object to overcome the gravitational pull exerted by a celestial body, such as a planet or a star, and escape its gravitational field. It represents the speed needed to move completely away from the object without being pulled back.
The concept of escape velocity is derived from Isaac Newton's laws of motion and gravity. It depends on the mass and size of the celestial body from which an object is trying to escape. The greater the mass and size of the object, the stronger its gravitational pull and the higher the escape velocity required.
Escape velocity is calculated by considering the mass and radius of the celestial body. It is usually determined by the equation √(2GM/r), where G is the gravitational constant, M is the mass of the celestial body, and r is the distance from the object's center.
Escape velocities are crucial for space exploration as they determine the energy required to launch rockets, satellites, or spacecraft into space. If an object does not achieve the escape velocity, it will remain in orbit around the celestial body or eventually fall back due to gravity.
In summary, escape velocity is the minimum speed necessary for an object to overcome a celestial body's gravitational pull and escape its influence without being pulled back.

Etymology of ESCAPE VELOCITIES
The term "escape velocity" is composed of two words: "escape" and "velocity".
1. The word "escape" is derived from the Latin word "exscapāre" which means "to flee" or "to get away from". It is formed by combining the prefix "ex-" meaning "out" or "away" and "scapāre" meaning "to slip or escape". It originally referred to physically breaking free or eluding captivity.
2. The word "velocity" comes from the Latin word "velocitas" which means "swiftness" or "speed". It is derived from the adjective "velox" meaning "swift" or "fast". In physics, velocity refers to the rate at which an object changes its position in a specific direction, indicating both speed and direction.
