[QUOTE="Roundandround, post: 6280840, member: 671784"] [B]Homework Statement:[/B] Understanding between force and mass [B]Relevant Equations:[/B] Word Question in Body Background: My understanding is force and mass are two [B][I]different things[/I][/B]. [B][I]Mass [/I][/B]is how much matter is in a body [B][I]Force [/I][/B]is mass multiplied by an acceleration. Here on earth, that acceleration is 32.2 Ft/s2. Therefore, for the same [I]mass[/I], there can be different forces depending on the acceleration. So, in English units, [B][I]what is the mass of an 180 pound person, where 180 pounds is the force (F)?[/I][/B] i come up with: [B]mass[/B] = F/a = 180 lbs/32.2 Ft/sec2 = 5.59lbs-sec2/ft. Not sure what I am doing wrong [INDENT][B]Where have I gone wrong with the units? [/B][/INDENT] [INDENT][B]What should be the proper unit for mass in english units?[/B][/INDENT] Looking on line, some examples just convert the 180 pounds to kg, and announce [B]81.6kg [/B](180/2.2) as the answer. How can 81.6 kg be a [B][I]mass [/I][/B]when 180 pounds is a [B][I]force [/I][/B]and not a [B][I]mass[/I][/B]? Many thanks for the help [/QUOTE]
