What is escape velocity?
Hello naked scientists, I love your show. My name is David, I'm from Vancouver Canada
What does escape velocity refer to exactly. It seems that if I have a tall enough ladder, i could climb up at any velocity and escape earths gravitation field, kind of like the space elevator concept. I would never need to reach that escape velocity. please clarify.
thanks naked scientists, keep up the great work
We put this question to Andrew Pontzen...
