EarthCalc

"ENTER" box for your calculated results for "g" and the Mass of the Earth.¹

READ THIS AND TAKE HEED: You are looking for the final quantity, which is "calculated Mass' or specifically the mass of the Earth. Unfortunately, Javascript presents this with far too many digits, so you will need to round off. For instance, if it says "6.81924759099256E+24" it means "6.81924759099256 times 10²⁴ ". That is a bit misleading, as there are too many digits, or numerals after the decimal point. You should round it off to say, 6.82 times 10²⁴. Do the same with whatever your reading is. That would be your result for Mass. Similarly round off the result for "g." If you fail to round off your results, I will count off. Also be sure to incluide the units (kg).

Copy the result for "Mass" and for "g" into your data table for each of the 10 trials.
