 unit work = unit force× unit distance = kg×(m/s2)×m  
 
hence work is directly prportional to mass and inversely proportional to time.
 
if new mass unit is doubled and new time unit is halved then  new work   = begin mathsize 12px style fraction numerator begin display style 1 half open parentheses k g close parentheses apostrophe m end style over denominator open parentheses 2 space s apostrophe close parentheses squared end fraction cross times m space space space equals space 1 over 8 fraction numerator open parentheses k g close parentheses begin display style apostrophe end style begin display style space end style begin display style begin display style m end style squared end style over denominator begin display style open parentheses s apostrophe close parentheses squared end style end fraction space equals space 1 over 8 space n e w space w o r k space u n i t end style
hence 8 joule = 1 new work unit
