Well, let me break it down for you Rk Naresh, buddy. I am not much familiar with this, however, trying my best to answer this question using the best of my knowledge.
First things first, escaping Earth's gravity is no walk in the park. A spaceship in Earth's orbit is essentially caught in a cosmic tug-of-war. To escape, it needs to overcome the gravitational pull, and that means reaching a certain speed. This magical speed is called the escape velocity.
Now, the force that's keeping our atmosphere cozy around Earth is gravity. Earth's gravity is like an invisible force field that clings to everything, including our atmosphere. It's what makes sure we don't all just float off into the vastness of space.
So, imagine a spaceship revving up to escape velocity. Once it hits that sweet spot, it can break free from Earth's gravitational embrace and venture into the cosmic wilderness. But until then, it's doing its orbital dance, playing tag with gravity.
And there you have it, my friend Rk Naresh. The escape from Earth's gravity is a calculated dance of speed and physics, and gravity is the invisible force that keeps our atmosphere wrapped snugly around our blue marble.
