The earth moves 40,000km in 24hours, so +/- 2000km/hr as we sit in front of our computer. Did you evre thing of that?

maybe this what makes us older.. our poor bodies exposed to this gravity? everyday, all the time?

WELL DONE WellTraveled..., that is exactly it :-)

It's more far-out than that...
Not only is the earth rotating on its axis, it's moving in its orbit around the sun. The sun (and us along with it) is orbiting the center of the milky way galaxy. The milky way galaxy is moving through space in a gravitational dance with the local group of galaxies...and while all of this is going on, space is expanding.
From the point of view of an observer at rest, your total velocity when all those factors are combined would be something around 160,000 km/hour. Yippee! :)

Actually, you're just a little off.
The Earth is orbiting the sun at a speed of about 107,200 km/hr.
The Earth is also rotating about its own axis at about 1675 km/hr AT THE EQUATOR. Your own speed due to rotation can be found by multiplying the cosine of your latitude by 1675 km/hr.
At some point during the day, the spot on Earth that you're sitting on is moving the same direction as the center of the Earth about the Sun, making your speed 108,875 km/hr at that particular time. At some point during the day, the spot on Earth that you're sitting on is moving the opposite direction as the center of the Earth, making your speed a mere 105,525 km/hr.

Hmmm, I just shot my laser pointer out my office window into space. Even with the earths rotation, motion around the sun, and galactic velocity, I am still only traveling 299792 km/s away from those photons I created. Whats up with that?

I think you need to get a new calculator... If the earth travels 40,000 km in 24 hours = 40000/24 does not equal 2000 km/h, it equals 1666.7 km/h.
And no, I don't think of stuff like that. Motion is relative. I'm not moving at all right now.

With respect to the center of the Earth, your speed is 464 m/s, assuming of course you are at the equator. Your speed as a function of latitude is s = 464cos(theta) m/s. Figure out what the latitude is of your location, substitute it into that equation, and that is your speed with respect to a line perpendicular to the equator originating from the center of the Earth.

Yes, Desert, but I'm so busy with other things that it's not on the top of my list.

Yes, thought of that, it's gravity.
