text: Changes in elevation become smaller throughout the track's course, as some mechanical energy is lost to friction.
text: The energy is never destroyed, but is lost to friction between the car and track.
text: Now that the coaster is whipping around loops and other hills, its energy is being lost to other forces like friction (energy created by two things being rubbed together) and air resistance.
