Momentum and Impulse

Key Questions

  • Answer:

    underbrace(bbJ = int_(t_1)^(t_2) bbF \ dt)_("Impulse") = underbrace(bb p_2 -bb p_2)_("Change in Momentum")

    Explanation:

    Newton's 2nd Law:

    • bbF = dot bb p

    implies underbrace(Delta bb p = dot bb p Delta t)_("Change in Momentum") = underbrace(bb F Delta t)\_("Impulse")

    In integral form:

    underbrace(bbJ = int_(t_1)^(t_2) bbF \ dt)_("Impulse") = underbrace(bb p_2 - bb p_2)_("Change in Momentum")
