Question: Two facts: A freely falling object at Earths surface drops vertically 5 m in 1 s. Earths curvature drops 5 m for each 8-km tangent.

Two facts: A freely falling object at Earth’s surface drops vertically 5 m in 1 s. Earth’s curvature “drops” 5 m for each 8-km tangent. Discuss how these two facts are related to the 8-km/s orbital speed necessary to orbit Earth.
