PhyzJob: Weight of the Worlds
Neelix
On your next voyage to distant planets, you can determine the acceleration due to gravity by weighing
standard masses as well as dropping objects to check their acceleration. You have with you the following
masses and weights originally marked on Earth. [On Earth, g = 9.8 m/s2.]
A: m = 1.0 kg
B: W = 1.0 N
C: m = 25 kg
D: W = 12 N
_________
W = 9.8 N
0.10 kg
_________
245 N
_________
1.2 kg
_________
From the information given, fill in the missing information regarding the weight and mass of the objects
on other planets. [Hint: It may be helpful to calculate the weight of A & C and the mass of B & D on
Earth first.]
