Effect of centrifugal force on ocean and earth
{"Image DocumentName": "Effect of centrifugal force on ocean and earth", "Image ImageDescription": "Centrifugal force acts on the ocean and earth. It is pointed outward away from the rotation axis. Therefore it is maximum at the equator (maximum radius from axis) and minimum at the poles (0 radius). \uf057 = x 10-4 /sec. At the equator, R ~ 6380 km so \uf0572R = .032 m/s2. Compare with gravity = 9.8 m/s2. Centrifugal force should cause the equator to be deflected (0.032/9.8) x 6380 km = 21 km outward compared with the poles. (i.e. about 0.3%) A = 6000 km; omega = 2pi/86400 sec = 7.292e10-4/sec. Omega2 a cos(latitude) = 3.17 cm/sec2 x cos(latitude) Compare 3.17 with gravity of 980 cm/sec2. Earth surface should be 0.3% farther out at equator = 20 km.
