Centripetal acceleration of Earth around Sun. #1. blue5t1053. Problem: The earth's orbit (assumed circular) around the sun is 1.5e11 m in radius, and it makes this orbit once a year. What is the centripetal acceleration of the earth? Equations: a = (v^2) / r T = (2*pi*r) / v My work: T = (2*pi*r) / v; 1 year = (365 days / 1 year)*(24 hours / 1 day)*(60 mins / 1 day)*(60 secs / 1 min) = 3.1536e7 s;
At the surface of the Earth, the acceleration due to gravity is roughly 9.8 m/s2. The average distance to the centre of the Earth is 6371 km. Using the constant k, we can work out gravitational acceleration at a certain altitude. Example: Find the acceleration due to gravity 1000 km above Earth's surface. â´ Distance from centre of Earth is 7371 km. â´ Acceleration due to gravity 1000 km above Earth's surface is 7.3 m/s2 (2 s.f.). Gravitational acceleration at the KÃ¡rmÃ¡n line, the boundary between Earth's atmosphere and outer space which lies at an altitude of 100 km, is only about 3% lower than at sea level.
