What do you meant by kilogram force and write its relation with newton?
One kilogram force ( 1 Kg f) is the force required to lift a body of mass 1 kilogram. 1 Kg f = 9.8 N #Workdone
Establish the relation between Newton and Dyne
1 N = 1 Kg x 1 m / sec2 = 1000 gm. x 100 cm / sec2 = 105 gm. cm / sec2 1 N = 105 Dyne [ 1 gm. cm / sec2 = 1 dyne ] #Workdone
