Earth gravity at altitude

WebEarth has a surface gravitational acceleration that is 9.8m/s2. (a) Earth’s radius is 6978km; at what altitude does the gravitational acceleration become half the surface acceleration? (b) What is the orbital period of a satellite orbiting at this altitude? Give your answer is reasonable units. WebThe MSL, approximated by an ellipsoid, is related to gravity or the center of mass of the earth. Discrepancies between a WGS84 ellipsoid, and the geoid vary with location. To continue with this example, elevation …

WebAt different points on Earth's surface, the free fall acceleration ranges from 9.764 to 9.834 m/s 2 (32.03 to 32.26 ft/s 2), depending on altitude, latitude, and longitude. A conventional standard value is defined exactly as 9.80665 m/s 2 (32.1740 ft/s 2). Locations of significant variation from this value are known as gravity anomalies. The mean orbital velocity needed to maintain a stable low Earth orbit is about 7.8 km/s (4.8 mi/s), which translates to 28,000 km/h (17,000 mph). However, this depends on the exact altitude of the orbit. Calculated for a circular orbit of 200 km (120 mi) the orbital velocity is 7.79 km/s (4.84 mi/s), but for a higher 1,500 km (930 mi) orbit the velocity is reduced to 7.12 km/s (4.42 mi/s). The launch vehicle's delta-v needed to achieve low Earth orbit starts around 9.4 km/s (5.8 mi/s). shard bridge hambleton https://dslamacompany.com
