Describe the real-world examples of Newton's third law that were identified in “Applications of Newton's Laws.”

Answer:

Real-world examples of Newton’s third law include rocket propulsion and the formation of mountains. When a rocket’s engines fire, gas is pushed downward out of the tail, which results in an equal and opposite force pushing the rocket upward. Similarly, when tectonic plates or layers of the Earth collide, they exert equal and opposite forces on each other, which can force the Earth upward and lead to the formation of mountains.
