On the moon the gravitational acceleration is approximately

On the moon the gravitational acceleration is approximately one-sixth that on the surface of the earth. A 5-kg mass is \"weighed\" with a beam balance on the surface \"on the moon. What is the expected reading? If this mass is weighed with a spring scale that reads correctly for standard gravity on earth (see Problem 2.1), what is the reading?

Solution

g(moon) = g ( earth) /6

Beam balance reading is 5 kg

Spring balance reading is in kg units

Force comparision length is directly propotional to F and F is directly proportional to g

So reading will be 56 kg
