**John**, Thursday, March 14, 2013 at 11:59pmIsn't "g" constantly -9.8 m/s/s, regardless of height?

**Nicole**, Friday, March 15, 2013 at 12:00amthat's what i thought but i put 9.8 and -9.8 in and the answer was wrong. so somehow it's different

**John**, Friday, March 15, 2013 at 12:03amThe effective value of g is inversely proportional to the SQUARE of the distance from the center of the earth.

The radius of the Earth is 6378 km. At 5100 km altitude, you are 11,478 km from the center.

g will lowered by a factor (6378/11478)^2
