leXX Posted October 29, 2002 Share Posted October 29, 2002 ... which direction is it travelling? The obvious answer is up of course, but there are some things you must take into account: The rotation of the earth The orbit of the earth around the sun The rotation of the galaxy The fact that the universe is expanding so what direction is it travelling in?

The obvious answer is up of course, but there are some things you must take into account: The rotation of the earth The orbit of the earth around the sun The rotation of the galaxy The fact that the universe is expanding so what direction is it travelling in? The answer is simple : it's traveling away from you (at least initially, unless you throw it above you). Rotation of the earth has no effect on it's direction. It's akin to throwing something inside a moving car - just because you're moving doesn't mean the ball or whatever travels faster or changes direction. Orbit does have something to do with it - if we were further away from the sun, there'd be slightly less gravity and the ball would travel further. If we were closer to the sun, we'd all be dying and have more serious things to worry about other than throwing balls around. Rotation of the galaxy again, has nothing to do with it - just like rotation of the earth. The fact that the universe is expanding also has nothing to do with it. Just a couple of observations from a guy whos had a LOT of physics. Link to comment Share on other sites More sharing options...
Count Dooku 2 Posted October 29, 2002 Share Posted October 29, 2002 A ball is a ball, no matter which way you throw it. That's good enough for me. Link to comment Share on other sites More sharing options...

Jah Warrior Posted October 29, 2002 Share Posted October 29, 2002 well, the way i understand it, you would need to know the exact center point of the univers to give a definitive answer, as a ll motion is relative to a starting point or origin. i dunno, its oneof those brain buster questions. pass me the coffee.

Kstar__2 Posted October 29, 2002 Share Posted October 29, 2002 becouse of the gravity, the ball will always go to the same direction (both up and down) but without gravity, it would be alot harder to tell Link to comment Share on other sites More sharing options...
C Shutt Posted October 29, 2002 Share Posted October 29, 2002 It's travelling up. Simple as that. Link to comment Share on other sites More sharing options...
TiE23 Posted October 29, 2002 Share Posted October 29, 2002 If it was an eclipce, newyears day at midnight 24:00 or 12:00am, I guess up to the sun, moon, to the stars (Milky Way) guess thats were it goes *head explodes, winches, and falls on the -keyboard- bleeding*gggggggggghkjjhbghjgjbnkblg nbymjjjjjjjjjjjjjjjjjj Link to comment Share on other sites More sharing options...
Count Dooku 2 Posted October 29, 2002 Share Posted October 29, 2002 If you throw a ball into the air... ... it comes back down again. Sometimes, the simplest answer can be the right answer. Link to comment Share on other sites More sharing options...
Eldritch Posted October 29, 2002 Share Posted October 29, 2002 Originally posted by Carl Shutt It's travelling up. Simple as that. 'Up' is a relative direction. What is up to you may not be up to someone else. To make your statement correct, substitute 'up' with 'away from you,' like I did. Y'all are making the problem waaaay too complex, lol.

Sivy Posted October 29, 2002 Share Posted October 29, 2002 Originally posted by Carl Shutt It's travelling up. Simple as that. oh yes but you're from austrailia, so someone from scotland would say that you are throwing it down i agree with JEDI_Anakin_S, you are throwing it away from you, covers all directions and the rotation of the earth etc. Link to comment Share on other sites More sharing options...

Clem Posted October 29, 2002 Share Posted October 29, 2002 it is travelling up we know this ... cos we said so ... up is the direction opposite to the earths pull so it is travelling up ... till it stops ... then falls down Link to comment Share on other sites More sharing options...
Pad Posted October 29, 2002 Share Posted October 29, 2002 i u throw a ball it doesnt mean it goes up. like u throw a ball to a basket ring. it goes a bit up, if the ring is at greater height then u, and away from u. also the spin u give at a ball is important. u could throw a ball up (in ur thought), but because of the spin the ball will go to the right (example). away from u covers it all i think. good 1 anakin Link to comment Share on other sites More sharing options...
gorganfloss Posted October 29, 2002 Share Posted October 29, 2002 If you throw a ball, no matter what direction you throw it, thats where its going. Link to comment Share on other sites More sharing options...
Clem Posted October 29, 2002 Share Posted October 29, 2002 also even if u take into account of all the orbits ... the only CHANGE in its direction is the small 1 up n down Link to comment Share on other sites More sharing options...
Havoc Stryphe Posted October 29, 2002 Share Posted October 29, 2002 I concur w/ JEDI_Anakin_S, According to Newton's second law of motion, an object in motion will remain in motion until acted apon by an outside force, the ball was already moving at the same speed and direction as myself before I threw it up, and since I too, am moving and rotating with teh earth at the exact same speed and direction, that motion is transferred to the ball. And according to Newton's first law of motion: An object will travel in a straight line unless acted apon by an outside force, the answer would be directly away and up from myself, but at the exact speed and direction of the Earth's rotation, revolutions and the universe's expansion. Thusly it would travel relative to the observer (That being myself) directly straight up and back down! Now to get the actual velocities and vectors we would need to know the exact center of the univers and the rate at which the "blue shift" for our galaxy and coincidentally our Earth. The likes of which I'd rather not deal with at the moment. (Can't think on an empty stomach!) Link to comment Share on other sites More sharing options...
Clem Posted October 29, 2002 Share Posted October 29, 2002 all of this is true ... but by definition up is the opposite of earths gravitational pull so it goes up Link to comment Share on other sites More sharing options...
Boba Fife Posted October 29, 2002 Share Posted October 29, 2002 Originally posted by JEDI_Anakin_S The answer is simple : it's traveling away from you (at least initially, unless you throw it above you). I would totally agree with this. It's direction of travel is relative to the person throwing it, i.e. me. Rotation of the earth has no effect on it's direction. It's akin to throwing something inside a moving car - just because you're moving doesn't mean the ball or whatever travels faster or changes direction. This I wouldn't totally agree with. If I'm in a car that's traveling 40 MPH, then, technically so am I and likewise; the ball. If I throw it, it's rate of travel has now just increased. Now, I realize that this counters the fundamental notion of Newtonian physics about an object at rest yada yada. Let's say I open the window with the ball in my hand. I drop the ball, what happens? Does it immediately drop straight to the ground? Nope. It undergoes a brief period of deceleration brought on by both gravity and wind resistence and then will hit the ground a good distance away from where I first dropped it. So, in essence, it already was moving. Orbit does have something to do with it - if we were further away from the sun, there'd be slightly less gravity and the ball would travel further. If we were closer to the sun, we'd all be dying and have more serious things to worry about other than throwing balls around. LOL!!! Not to mention the fact that the ball would melt. *psst* Anakin, it's "farther". One more word in the English language that should be stricken from the dictionary because it's too damn confusin'!!

Taos Posted October 29, 2002 Share Posted October 29, 2002 Well, this morning (for me anyways) has proved to be quite educational (I feel like I'm back at school).
