text: what would happen if earth spins faster.? what  would happen if the would start rotating at high speed. is it possible that objects would be thrown out from earth. but in the equation of gravity i.e. g=mass of the two objects/ square of the distance between them, then where does the centrifugal or centripetel force os in picture over here. if centrifugal force had to act then why does not the gravity acts at the north/south pole higher than at the equator , regarding to the fact that earth rotates at a tangential speed of 20,000 kmph at equator. there would be many more days in a year and since the earth also wobbles, there would be many more but much shorter milder seasons in a year. as it is now, i believe the earth tilts on its axis about 5 degrees of center meaning the spinning rotation and wobble are slowing down. therefore, a high speed rotation is indicative of the earth's rotation billions of years ago.
