  • Q5
    If a net force is applied to an object in the opposite direction of its motion, what will happen to the object?
    The object will remain at a constant speed
    The object will slow down
    The object will instantly stop
    The object will speed up

    8.PS.2b
  • Q6
    Which of the following best describes the effect of balanced forces acting on an object?
    The object remains at rest or continues to move at a constant speed
    The object decelerates until it stops
    The object changes direction frequently
    The object accelerates in the direction of the larger force

    8.PS.2b
  • Q7
    What effect does increasing the net force on an object have on its motion?
    It decreases the object's acceleration
    It keeps the object's speed constant
    It increases the object's acceleration
    It changes the object's direction without affecting speed
