Question

3) In calculating the work done in lifting an objectto a given height, it is necessary to use g if the mass is given inkg. The quantity g is not needed if the weight is given in Nbecause A ) a newton is a measure of force, and a kilogram isnot. B ) the rules of measurement are different . C ) a kilogram is a unit of weight. D ) the symbol for metric mass has the letter M. E ) only divide by g. 3) In calculating the work done in lifting an objectto a given height, it is necessary to use g if the mass is given inkg. The quantity g is not needed if the weight is given in Nbecause

Explanation / Answer

                  Work   done   = Force *displacement                     Force = mg in N                     weight   = mg  measured in N               if mass is given   we multiply g with mass forforce F         where as theweight is given why we need g that means                       force = weight = mg in this case only                     I hope this helps you!
