SOLAR SYSTEM

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: -Rockets, also called launch vehicles, play an important role in our lives. Rockets deliver satellites to space where they can begin to do their important work.

Detailed explanation-4: -Rockets have to tilt to the side as they travel into the sky in order to reach orbit, or a circular path of motion around the Earth. This steering technique is known as a gravity turn, which uses Earth’s gravity to help conserve rocket fuel and minimize stress and strain on the spacecraft.
