Questions and Answers

What is the equation for impulse?

  • $J = \frac{F}{\Delta t}$
  • $J = F + \Delta t$
  • $J = F\Delta t$ (correct)
  • $J = F - \Delta t$
  • What is the SI unit of linear momentum?

  • Kilogram-meter/second (kg·m/s) (correct)
  • Newton-second (N·s)
  • Kilogram-meter (kg·m)
  • Newton (N)
  • What is the equation for the impulse-momentum theorem?

  • $(\sum F)\Delta t = m(v_f - v_o)$ (correct)
  • $(\sum F)\Delta t = \frac{m}{v_f - v_o}$
  • $(\sum F)(v_f + v_o) = m\Delta t$
  • $(\sum F)(v_f - v_o) = m\Delta t$
