Questions and Answers

What does the law of conservation of momentum state?

  • The total momentum of bodies changes with time.
  • Momentum can be created but not destroyed.
  • The total momentum of bodies in an isolated system remains constant unless an external force is applied. (correct)
  • An external force is not required to keep the total momentum constant.

    • What is the direct consequence of Newton's third law of motion?

  • Conservation of energy
  • Conservation of velocity
  • Conservation of mass
  • Conservation of momentum (correct)

    • In a collision between two particles A and B, if particle A exerts a force on particle B, what does particle B do according to Newton's third law?

  • Particle B exerts an equal force in the same direction.
  • Particle B exerts a greater force in the opposite direction.
  • Particle B exerts an equal force in the opposite direction. (correct)
  • Particle B exerts a smaller force in the same direction.
