It relates to the relativity shit that has raised its ugly head elsewhere, but hey, if you are always here posting and reading this shit, you already know that.
Quick summary: An object on the equator is said to be "moving" at around 1037 mph because the earth rotates once a day and the circumference is about 24,901 miles, and yes the reason the math works out so well is because the 24 hours is based on the complete revolution of the planet, herp derp, but let's make it simple and say 1000 mph
Here's a source so you don't try and impeach what I just wrote
Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour.
No, that is not true, in fact it is
In other words, it is garbage, worthless, and it s complete in it's worthlessness
I realized this quite simply by trying to place a camera in a location to show this. I use astronomy software, which is really fucking cool as shit, and to make a movie (animation really) of anything, you simply have to pick a location for the camera. You can't avoid this, the software has to know where your virtual location is in order to render anything.
And before the pedant shows up, Speed is the rate of motion, or equivalently the rate of change of distance.
Speed is a scalar quantity with dimensions length/time; the equivalent vector quantity to speed is velocity. Speed is measured in the same physical units of measurement as velocity, but does not contain the element of direction that velocity has. Speed is thus the magnitude component of velocity.
To say you are "moving east at 1000 mph" is a velocity measurement, but to have such a measurement, you have to choose a reference point. There is no point that you can choose to get a velocity of 1000 mph eastward, this is due to the laws of physics, as well as the acceleration of a spinning point.
The only possible point to choose would be a rocket or airplane flying 1000 mph west from your location, from which one could say you are moving eastward at that velocity, except it is a curving motion, so the velocity changes rapidly. (acceleration)
Which is why the speed of an object on the equator wouldn't be 1000 mph, but a rapidly changing velocity, until the rocket or airplane reached the opposite side if the earth, at which point it would reverse.
There is quite literally no other place to put a camera, especially to measure a 1000 mph speed.
So no, an object on the equator is not moving at 1000 mph. In fact, it isn't moving at all. Unless your point you measure it from is moving, but even then, you never get a 1000 mph measurement of speed. It's not physically possible.
