Explanation:
Escape velocity is the minimum speed that an object needs to be traveling to break free of a planet or earth's gravity well and leave it without further propulsion. For example, a spacecraft leaving the surface of Earth needs to be going 7 miles per second, or nearly 25,000 miles per hour to leave without falling back to the surface or falling into orbit.
Hope you would like it
