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!
