1. The problem statement, all variables and given/known data
A number of objects are taken to the moon, where the acceleration due to gravity is about 1/6 of earth's.Complete the following table: ItemMass on EarthMass on MoonWeight on MoonWeight on Moon Paper clip 1.2 g  g g(f)  dyne Can of cola 0.56 lb(m)lb(m) lb(f)   pdl Hammer1.3 kg kg kg(f)  N 2. Relevant equations 3. The attempt at a solution I think the mass on Moon will not change..right??! the weight on Moon(the third column ) = mass*9.8*1/6 ...!! what is ( dyne, pdl,N)?!! How to convert to these units ?? THANX =)

Moon weight = mass * g * (1/6)The numerical value of g depends on what system of units are being used. It's 9.8 m/s^2, but if you use cm or inches then it would be different than 9.8 pdl is an abbreviation for poundals (different than pounds) N is Newtons.

Thank you very much.. Where can I get the formulas to convert into these units?!

To convert 9.8 m/s^2 into the other units, use these facts:
1 m = ____ cm? 1 m = ____ inches? From those conversion factors, use the normal methods for converting units. You might try a google search to see what dynes, poundals, or Newtons are. But your teacher/professor really should have talked about these in class already. Seriously, if he did not at least discuss what a Newton is, he should be fired. EDIT. The poundal is a rather obscure unit. I did find this info: http://en.wikipedia.org/wiki/Poundal
