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

Answer:

Newton's third law states that for every action, there is an equal and opposite reaction. Real-world examples include a rocket engine, where the downward push of escaping gases creates an upward thrust on the rocket. Another example is the formation of mountains, where tectonic plates collide and push against each other, forcing the Earth's crust upward.
