Classify action-reaction forces — free printable Middle School Science worksheet

Middle school students classify action-reaction force pairs in this Physical Science worksheet, applying Newton's third law to identify which force pairs are valid examples and which are not. Teachers can use it as a formative check after introducing the third law, asking students to justify their classifications with reference to the key idea that action and reaction forces always act on different objects. The skill is essential for solving more complex force diagrams later in the unit.

Learning objectives

  • Classify force pairs as valid action-reaction examples based on Newton's third law
  • Explain why action and reaction forces act on different objects in each pair
  • Distinguish Newton's third law pairs from other force interactions in physical scenarios
