What is the tallest hill your train can make it over?

Multiple Choice

Where does the train get its energy to make it up the hills?

• The train gets its energy from the tracks.
• The train gets its energy from the air it passes through.
• The train gets its energy from the passengers pushing it.
• The train gets its energy from elastic potential energy stored in the spring of the launcher.
