Original Note:
Centrifugal force increases with the square of angular velocity, not tangential speed. The relation is: F=mrω² At 1 m radius and 10 km/h tangential speed, the merry-go-round would spin at ~27 RPM. Earth spins much slower, at one revolution every ~24 hours (<0.0007 RPM). https://en.wikipedia.org/wiki/Centrifugal_force https://en.wikipedia.org/wiki/Angular_velocity https://en.wikipedia.org/wiki/Tangential_speed
