Final answer:
Mrs. Jewis likely demonstrated the concept of gravity to children by pushing an object out the window, illustrating how it falls toward the Earth due to gravitational attraction.
Step-by-step explanation:
The question seems to revolve around a concept from physics related to gravity. Mrs. Jewis, as depicted in the question, was likely demonstrating to children how gravity works, possibly by dropping an object out the window to show that it falls toward the Earth due to the gravitational pull. This is in line with physics education, where practical demonstrations are used to help students understand fundamental concepts like gravity.
Another key principle of gravity that relates to the question is that inside a freely falling box or spaceship, people will experience weightlessness. This is because everything inside is falling at the same rate due to gravity, creating an environment similar to that of astronauts aboard the International Space Station (ISS), as described in the provided reference material.
