hello. the question is: if i have an exact model (and i mean EXACT) of, say, a glider (you know, those whaddamacallits, white things, long, thin wings, those ones), if i have one of those, why will it not fly as well as a proper one? (the model is a lot smaller than the real thing) i was...

It's called Orbiter, and you can get a free copy here: http://www.medphys.ucl.ac.uk/~martins/orbit/orbit.html Fly several different spacecraft (both VTOL and HTOL) around the solar system. The learning curve is very steep due to the physics engine; you can't get to the moon just by...

Wow, last flight of the Concord was today. Sad sight seeing it. I am not sure but I hope there is some replacement in the works but I am not sure. Did they decommision them because of their age or lack of market?

Hi Everyone! Like always, thank you for helping me figure out my last physics question! I greatly appreciate the help. Here are my next questions: Q: Determine the speed at which a baseball must move in order for air resistance to be significant? A: mg = ½ * Cd * A * pair * v^2 pair =...

Here's the question, A stone is thrown vertically upward with a velocity of 26.0 m/s from the top of a tower having a height of 18.5m. On it's return it misses the tower and finally strikes the ground. What was the elapsed time of the flight stone? I started if off with delta y=...

The secret of antigravitational flight, as told by ETs In an UFO forum, where I´m the resident skeptic, some one gave me this contactee message, given to him by a ET, that is some kind of Physics unknown to humanity, and that is the secret of antigravitational flight. I know almost...
