Okay, so for the last few months in physics we've worked on the kerbal space program, and although my group didn't really accomplish much, i kinda just wanted to finalize a few things that i learned. So there is my top 5
1) Kerbals are easily startled. meaning, these kerbals are astronauts that should have been previously trained and have experienced the forces existing in a spacecraft or spaceplane in the game. clearly this was bypassed as much as the safety measures on my rockets
2) Orbit CAN be achieved, around anything. if you think that you will randomly drift out to space when you launch a rocket, that turned out to be a rare occurrence for me. I often would randomly test out a rocket to see if it was too heavy or light to do anything, and it would drift off, past orbit, and then into orbit of the sun, right near kerbin.
3)Air intake does not work in a vaccuum. and for those of you that think its a no brainer, i went into this with no previous rocket science training besides the universal F=ma and g=9.81m/s2 Therefore, i had no idea that on the alpha version of a game that they could differentiate atmospheres from space, but CLEARLY by the plummeting altitude and increasing velocity of my ship, that would be a 'NO'
4) Kerbal's Mun is really hard to get to if you have no idea what you're doing, but look up a single video and orbit 'slingshots' make a heck of a lot more sense.
5)if all else fails, every physics class can be the fourth of july (with satellites, not kerbals PLEASE)
