   What is escape velocity in physics?

   • In celestial mechanics, escape velocity or escape speed is the minimum speed needed for an object to escape from contact with or orbit of a primary body, assuming: Although the term escape velocity is common, it is more accurately described as a speed than a velocity because it is independent of direction.

    Dec 5, 2022 · Escape velocity is defined as the minimum velocity required for an object to escape the gravitational force of a large object. The sum of an object's kinetic energy and its gravitational potential energy is equal to zero. The gravitational potential energy is negative due to the fact that kinetic energy is always positive.
