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

    Theory: During the early part of the seventeenth century, Galileo experimentally examined the concept of acceleration. One of his goals was to measure the acceleration due to gravity, or the acceleration of freely falling objects. Unfortunately, his timing devices were not precise enough to measure the free fall time directly. He decided to “dilute” gravity by using fluids, inclined planes, and pendulums.…

    The mass measurements (in grams) of sphere 1 are 23.7 grams on the balance beam and 23.1 grams on the electronic balance. We can at least confirm that sphere 1 is about 23.0 grams. In terms of sphere 2 the mass measurements of the beam are 68.6 grams and 68.0 grams on the electronic balance. Akin to the idea that we had with sphere 1, we can assume that sphere 2 is about 68.0 grams.…
