Explanation:
Detailed explanation-1: -Rockets don’t go escape Earth’s gravity by launching directly from the surface. Rather, astronomical engineers first send these rockets into orbit and then use orbital velocity as a slingshot to propel a rocket to its necessary escape velocity.
Detailed explanation-2: -If you want to escape the gravitational clutches of the Earth altogether, you must achieve a speed of at least 11.2 kilometers (or about 7 miles) per second, which is around 33 times the speed of sound.
Detailed explanation-3: -Example: Flying planes and deploying satellites are two examples. As aircraft and satellites are able to escape the earth’s gravitational pull.
