Question

what will happen if the earth starts rotating at a. slower speed
​

Answer 1

If it was slower then one full rotation would take more than 24 hrs., thus making days & nights longer. Our weight would be more, because as the Earth would rotate slower, it would exert less centrifugal force on us. The resultant force of the Earth's gravity and the centrifugal force would be more as gravity would remain constant but centrifugal force would decrease. There would also be a temperature change as each hemisphere (Eastern and Western) would get more time to warm up from the Sun's rays.

Answer 2

it always rotate in medium speed
