Heres a highschool physics question thats got my g/f stumped Need help:) Here is the question. Because the earth rotates once per day, the effective acceleration of gravity at the equator is slightly less than it would be if the earth didn’t rotate. Estimate the magnitude of this effect. What fraction of g is this? Here is the answer= 7. 3.44 x 10-3 What she needs is the work that gets that answer so like the necessary equation to come up with it. Any help would be highly appreciated. THANKYOU!!!
