You're doing homework again. This ain't rocket science.
At the equator, the spin speed is 1040.4 miles per hour.

Exact is obviously impossible.
There are several ways to measure the spin of the Earth. The value measured depends on the frame of reference chosen.
For those of us on the surface of the Earth it appears that the universe revolves about the Earth about once a day.
For an observer on the moon the Earth would appear to rotate a little less than once a day.(about 48 minutes less)
For an observer on the Sun the Earth would appear to rotate closer to once a day.(about 5 minutes less than a day)

people do fall to the floor because of the fact of gravity. i think of the spinning of the earth(rotation) and its revolution are additionally simply by gravity. Gravity is an attracting tension. it relatively is the tension that holds each and every thing mutually. it makes the debris of which the celebs and planets are made coalesce to sort the heavenly bodies, and it governs the varieties of photograph voltaic structures and galaxies. each and every thing with mass is interested in each thing else with mass. yet they don't in ordinary terms shoot quickly at one yet another, because of the fact there are each and every style of different gadgets with gravity appearing on them. They circulate till they attain a place of relative stability, the place the forces are equalised, and the revolutions and rotations sort area of that rather good state. There are alterations in the speeds with which the earth spins or travels. we don't be conscious them nevertheless. some are laid low with the movements of the different planets, or perhaps by making use of the climate in the international. Are you difficult gravity with centripetal tension or centrifugal tension? those are to do with spinning, not gravity. Centripetal tension is the tension required to make an merchandise revolve, the centrifugal tension is the reaction to the centripetal tension. Neither have something to do with gravity.

At the equator, just about 1038 mph.
At the mid-latitudes, about 700-900 mph

One revolution per day (1 R.P.D). Just kidding. Its 24,900 miles (circumference of the earth) divided by 24 hours. so about 1037 miles per hour.
