In the passage, "friction" refers to "a force that arises between matter and that moves against other matter." It describes how friction acts between the wheels of the roller coaster and the track, as well as the wind resistance, both of which contribute to slowing down the roller coaster cars.
Read the passage from "The Physics of Scream Machines."
A second force also works to slow them down. This force is called friction. Friction can be produced by wind blowing against a rolling car and by the metal surface of the wheels pushing against the metal track. Friction helps roller coaster cars slow down as they approach the station.
