>>13568682>how strong would the gravity be on the surface of an earth that is 10x as massive, but just as dense as the normal oneGravity on normal earth is
Supposing the average density is the same and mass is 10x as great, . Lastly,
your friend was exactly correct and had every right to be smug I guess. g grows slower with mass (linearly) than it shrinks with radius (quadratically).
>but the part that fucked me was the N . m2 /kg2, which i didn't get how to use or determine exactly.that's called the universal gravitational constant and it was determined experimentally with a torsion balance and some masses by Cavendish in the 18th century (AKA his "weighing the earth" experiment
