Question
The fastest trains in the world ride on a cushion of air. Use what you learned today to write a hypothesis about why those trains can go so much faster than the trains we have here in the Unites States.
Solution
Based on the information provided, a possible hypothesis could be:
"The fastest trains in the world can travel at higher speeds than trains in the United States because riding on a cushion of air reduces friction. In the United States, most trains run on traditional rail tracks, where there is a significant amount of friction between the train wheels and the tracks. This friction limits the speed at which the trains can safely travel. However, trains that ride on a cushion of air, also known as maglev trains, do not have this limitation. The magnetic levitation (maglev) technology allows these trains to hover above the tracks, eliminating the friction that would normally be present. This lack of friction allows the trains to reach much higher speeds. Therefore, if the United States were to implement maglev technology in its train systems, it could potentially increase the maximum speed of its trains."
