Hi, me again. I have another question concerning the gravitation equation. My physics book shows through a proof that the escape velocity of an earth satelite is just [tex]sqrt(2)[/tex] greated than the orbital velocity. But I am having trouble seeing how this is so. My instinct tells me that if I increase the velocity by [tex]sqrt(2)[/tex], I will start to move out farther in space, but as a consequence I will also increase my radius, until which point I have achived the right speed/distance to become a satelite again, but this time at some further distance from the earth. I dont see how increasing my speed by the square root of two will allow me to drift off into space and no longer stay in orbit. Part 2. Lets say I have a delta V rocket that can go the escape velocity of 25kmi/hr. Now, lets also say I have an estees model rocket that can go 50mi/hr. Clearly the delta V has the required velocity to go off into space. What happens to the model rocket at 50mi/hr. If fuel is not an issue, it will always be going at 50mi/hr. Wouldent this small model rocket go off into infinity also. Is there a conflict with the equation to find the escape veloctiy then?, since I could send a delta V at 25kmi/hr or a meager model rocket at 50mi/hr off into infinity? Cyrus Abdollahi.
