Knock out the false force pair claims

Read exercise and reference answers
Questions
  1. Question
    Three of these claims about an action and reaction pair are false.
    Choices
    1. Item
      The two forces act on different bodies
      Correct
      Yes
    2. Explanation
      They act on different bodies, so neither can cancel the other.
      Item
      The two forces cancel each other out
    3. Explanation
      A rocket pushes out gas and works better with no air at all.
      Item
      A rocket pushes on the air behind it
    4. Explanation
      The two forces are equal in size and opposite in direction.
      Item
      The reaction is weaker than the action
Instructions
Tap the three false statements about action and reaction pairs to clear them away.
