Help me understand this please.
Why is the escape velocity of Earth so fast? Doesn’t the gravitational pull of the Earth weaken as you get farther away from the center of the Earth?
I can jump a couple feet into the air… I’m am going upwards nowhere near 27k miles an hour… if I could leverage my feet on air, couldn’t I apply the same amount of force to go another few feet in the air until I escape the Earth? High altitude balloons can almost escape Earth and are going nowhere near 27k miles an hour. Yet I know, (because I have heard it many times before) that the escape velocity of Earth is about 27,000 miles an hour.
Why can’t you go upwards at 1 mile an hour until you escaped Earth?
What’s the scoop?
Thanks,
