What can be inferred about the action and reaction forces from the observations of a student letting a balloon go?

• The forces act in the same direction.

• The forces are unequal in magnitude.

• The action force results in the formation of the reaction force.

• The reaction force is larger than the action force.

The student concludes that the acceleration of an object depends only on the force

applied on the object.

Why should the student revise the conclusion?

• The student only uses two marbles in the experiment.

• The student does not describe the force of each push effort in units of Newton.

• The student does not consider the effect of mass on the motion of the marble.

• The student only tests the motion of the marble on one type of surface.
