Newton's second law

  1. May 24, 2010 #1
    1. The problem statement, all variables and given/known data
    How can Newton's 2nd law be derived for a single body in an 1Dimesional case ?


    2. Relevant equations
    F=m(du/dt)

    3. The attempt at a solution
    It is given that the principle of conservation of energy must be used,for the derivation.
    Are there any more hints?

    No more hints are needed. Conservation of energy means that energy does not change with time, i.e. the rate of change of energy with respect to time is zero. Therefore ...
