Comments/ critiques on my explanation and examples of lbl vs. lbf? http://www.scribd.com/doc/85548870/Conversions-Involving-Lbl-Lbf-Lbm-and-Slugs Are there any other good examples you can think of to give someone who is just learning the English system of force and mass?

    We need to comment a lot about the writting but the most important is to solve the problems. Sorry I'm a little to much slow =P.

    That's okay! I just had a lightbulb pop up in my head when I realized that I could explain this stuff better than how it was explained in the packet that my instructor gave me.

    I have uploaded a revision of my document with more examples :-) http://www.scribd.com/doc/85548870/Conversions-Involving-Lbl-Lbf-Lbm-and-Slugs My goal was to beat the living hell out of this concept... a lot of the people in my class were just NOT understanding.

    I don't know =(. Actually I did not know the unit called poundal.

    The things your wrote are very logically indeed and it seems to me that is right.

    But I'm not completly sure because I can not understand yet the conversion between slugs and lbm.

    I thought that the lbm was a unit of mass. Now I'm very confused about it.

    Slug to lbm is similar to saying kilogram to gram. lbm is just a scaled-down version of slugs. lbm and slugs are both mass.

    lbl and lbf are units of force.

    I meant... an object of a mass of 2 slugs on earth will be 2 slugs on Pluto... or wherever.

    I think once you really GET this basic stuff on lbm, slugs, whatever... then all the other stuff involving these units becomes really easy. (But when I'm ruler of the universe, anyone who so as mentions gallons, slugs, lbm, etc. will be be-headed on the spot)
