Thanks a lot man, that actually makes sense :)

Sorry for the long quote, but this guy on another thread responded to a similar question by saying, Mentor's note: Edited to give proper quote.

Well, I heard that if there's the forcebof gravity pulling it down, and momentums pushing it out, then the total force would be zero, and it would travel in a straight line

The reason I ask, is that a lot of people seem to say the momentum of the craft is not the reason it stays in orbit, but then NASA says it is, so... :)

Would you guys agree with these websites on how orbits work? http://www.nasa.gov/audience/forstudents/5-8/features/nasa-knows/what-is-orbit-58.htmlhttp://www.qrg.northwestern.edu/projects/vss/docs/space-environment/1-what-causes-an-orbit.html

Oh, OK, that makes sense, thank you

But then what causes my example to happen?

Yes, but something with a lot of momentum is hard to stop or change direction, right? So it seems that more momentum means its harder to change speed or direction

Wait, so what IS momentum? If something has more momentum, it's common sense that it's harder to stop, or change direction. Like a truck going at 1 mph vs 120 mph

Hi. So I know that inertia (the resistance of an object to a change in its velocity) is reliant on mass. I also know that momentum is mass times velocity. So momentum is really inertia times velocity. My question is: if that's so, is momentum then not a measure of a moving object's inertia, its...
