Questions and Answers

What is the formula for momentum?

  • Momentum = mass + velocity
  • Momentum = mass × velocity
  • Momentum = mass - velocity (correct)
  • Momentum = mass / velocity

    • According to the principle of conservation of momentum, what happens to momentum if no external force acts on it?

  • Momentum changes direction
  • Momentum is created
  • Momentum cannot be created or destroyed (correct)
  • Momentum is destroyed

    • What does Newton's second law of motion relate to?

  • The rate of change of momentum of a body (correct)
  • The rate of change of acceleration of a body
  • The rate of change of velocity of a body
  • The rate of change of mass of a body

    • If a force $F$ acts on a body with mass $m$, and the initial velocity is $V_1$ and final velocity is $V_2$, what is the relationship between these quantities?
