Question

what is escape velocity?​

Answer 1

The initial velocity needed to achieve that condition is called escape velocity. From the surface of the Earth, escape velocity (ignoring air friction) is about 7 miles per second, or 25,000 miles per hour. Given that initial speed, an object needs no additional force applied to completely escape Earth's gravity
