      Derive the unit of force using the second law of motion. A force of 5 N produces an acceleration of  on a mass  and an acceleration of  on a mass . What acceleration would the same provide if both the masses are tied together?

    Answer:

                                           From Newton's second law, F = ma SI unit of mass,          m = 1 kg SI unit of acceleration,     a. = 1 ms SI unit of force, is known as 1 newton (N) 1 newton                       (1) 1 newton can be defined as, "The force is said to be 1 newton if it produces 1  acceleration in a body of l kg mass".      (1)                                        From   or(1/2) Similarly,                                                         (1/2)                                                                          (1) Acceleration produced by the same force provided if both the masses are tied together.                        (1)
