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;
The acceleration due to gravity on Earth rounded to the nearest hundredth is -9.81 meters per second squared. This means that if no forces other than that of gravity are present, then for every second an object is falling, its velocity towards Earth increases by 9.81 meters per second. Negative acceleration does not necessarily mean that the object is slowing down.
