Questions and Answers

What will happen to the motion of a luggage cart if the net force on it is 0 N?

  • The cart will stay still (correct)
  • The cart will change direction
  • The cart will decelerate to a stop
  • The cart will accelerate forward

What happens to the motion of an object when an unbalanced force acts on it?

  • The object will maintain a constant velocity
  • The object will accelerate (correct)
  • The object will decelerate to a stop
  • The object will change direction only
