If that were the case, when we fly on planes at 30,000 feet , we would weigh even lighter again as you have now dramatically increased the size of the arc radius of the Earth .
An Ant walking on the hour hand or the Town Hall clock does not get thrown off when he reaches the tip and that is traveling TWICE as fast as the Earth is . We would only ever notice we are revolving at 1000mph if there was a fixed marker in our skies and attached to space .
Shameless too, how you blatantly use the word 'speed' instead of rpm's, or rpd's in the case of the globe rotating once per day.
Speed is distance covered in a time period. Your clock ant is speeding along at one foot per hour. A dead ant at the equator is spinning 1000 miles per hour.
Speed is speed is speed. Rim speed velocity is the true language to describe the motion of the outer edge of a spinning object. A fighter jet can fly in a straight line at 1000 mph. Or more. Put an ant on the wing of a jet and see how long before it would be knocked off.
Please don't put the ant inside the jet to make a false comparison. And then please explain how the air must sync speeds with the surface moving under it at over mach 1.
"A fighter jet can fly in a straight line at 1000 mph."
You dopey twit, you proved how brainless you are !
If in fact the "rim speed " of the Earth was actually 1000mph, the Jet , traveling at 1000mph could barely keep up with it and it could land like a Helicopter !!!!!!!!!
