Science Question #2

If you are moving on planet earth at X miles per hour and you take off in your car on the drag strip and reach X mph then... could you add those two numbers (assuming you accelerated in the exact direction the earth was moving of course) ?

Re: Science Question #2

Your question is "could you add these two numbers" so yes.

Any two real numbers can be added.

Re: Science Question #2

well you see, you have to have a reference point for speed. Earth rotates at x mph... say like 19,000 miles an hour or something like that, I can figure it up, but I'm too lazy, so I'm throwing that number out there. Anyway, we can say it's rotating at 19,000 miles an hour... and sure, if you go accelerate in addition to that, you could say you were moving at 19,150 mph... unfortunately, it requires you to have a reference point. For all our speeds, our reference point is the Earth, which means the Earth's speed relative to itself is 0. But, I suppose if you wanted to pick a fixed point not on the Earth's surface, an immoveable one, then you could say you were moving at 19,150 mph... but it's really a trivial point, because you could pick a different reference point, and be moving even faster! Hell, it doesn't even have to be in this galaxy.

Re: Science Question #2

if earth is only 25,000 miles in diameter, devided by 24 hours per full rotation........

id do the math but i do enough of that at work. if your job was to calculate exact square footage of a building, then price out panels based on that, and then write up qoutes, youd be saying "**** math" too.

Re: Science Question #2

the speed of Earth is trivial...

Re: Science Question #2

Also remember that while the Earth is rotating, it is also orbiting around the sun. In fact, our entire galaxy is also likely moving whether we know about it or not. If you believe in the Big Bang Theory, we are definitely moving away from where the bang occurred.

Some modern day phsyics theories have very interesting ideas on exactly what motion is. You get to the point where you realize that motion can only be described in relation to another object (hence, the theory of relativity). However, at a certain point, you arrive at a loss as to which "point" things are moving in relation to.

Basically, this question is mostly irrelevant. We measure our speed on Earth in relation to Earth's surface. Otherwise, where do we stop? Should we only measure our speed in relation to the "center of the universe"? If indeed such a place exists...

Remember, all this is coming from a guy with various pictures of caribou and a guy w/ a leprechaun hat in his sig. Take it as a grain of salt. Or maybe just a single NaCl molecule. Don't think it's worth the whole grain.

Re: Science Question #2

we take the reference point that most benefits us in the specific situation. It would be pretty foolish to talk about how fast a space shuttle was moving away from Earth, if it had to land on the moon... of course we would talk about its speed in relation to the surface of the moon. Of course, we should also use this when trying to land air craft on air craft carriers... and the like. That's the great thing about speed... and/or velocity, we can pick the reference point.

Re: Science Question #2

It doesn't matter what your frame of refernce is. You can add those two numbers together and get an answer.

The answer will vary based on the frame of reference but not the math.

So, yes Brandon, you can add any two real numbers. Just don't expect the result to necessarily mean anything significant.

Re: Science Question #2

that was what I was getting at the earth is rotating around the sun which is in our galaxy which is rotating around other things so how fast are you really going

Yes sir.

I assumed since he said it was a "science question" that he wanted a more scientific answer, rather than the simple "yes, you can add two numbers".

But as far as determining "how fast we are really going", it all depends on what point you choose to be as the reference for how fast we are moving. If you want a definite... "we are moving this fast in reference to the center of the universe", then I wish you much luck.

I personally think the center of the universe is somewhere in a bar just across the Tennessee state line, and all things in the universe originated from that point. But I'm at least partially retarded.
