A rocket pushes gases backwards and the gases push the rocket forwards. Which law does this illustrate?

Answer and explanation

Correct answer: C. Newton's third law: forces come in equal and opposite pairs

  1. Step 1: The rocket exerts a force on the gas.
  2. Step 2: The gas exerts an equal and opposite force on the rocket (Newton's third law).
Answer
Newton's third law: forces come in equal and opposite pairs.
Why not the others: Newton's first law: objects stay at constant velocity when no resultant force acts: this concerns a single object. Newton's second law: force equals mass times acceleration: this relates force to acceleration of one object. The law of conservation of charge: this concerns electricity.
