How do you solve the equation in Example 12.4? If there is no such thing as centrifugal force, why does the dictionary define it? In Module 8, On Your Own 8.10, why do I get a different answer than the one in the book? In Module 8, Test Question 8, if centripetal force depends on the inverse of r, why is the closer satellite the one that moves faster? In Physics, Example 8.4, the radius of the earth to only the distance of the other object from the earth's surface. Why wasn't the radius of the smaller object included as well? On Module 7 Test, Question 15, why did I get 4.2×10^11 instead of 4.5×10^8? Physics Sample Lab Report
