between the wheels of the car and the track
centripital motion, gravity, friction, ect.
Thermal energy is heat. Heat is associated with motion (like a roller coaster) because of friction. Friction slows down the speed of an object and changes some of its kinetic energy into heat.
A roller coaster experiences several forces, primarily gravity, friction, and centripetal force. Gravity pulls the coaster downwards, providing the potential energy that converts to kinetic energy as it descends. Friction between the coaster and the tracks opposes motion, while centripetal force is necessary to keep the coaster on its curved paths, particularly during loops and turns. These forces interact dynamically to create the thrilling experience of a roller coaster ride.
Gravity and Friction
liquid
yes; wherever the coaster touches the tracks there is static friction pressing against it and it pressing against the tracks, thus keeping it from flying off.
Upside down.
a roller coaster that's made from wood of course duhhhhhhh..... sike naw im just kidding a wooden roller coaster conducts more heat than a steel roller coaster because it has more rough edges and that creates more friction and that makes heat. o a wooden roller coaster conductes more heat than a steel roller coaster does.
Friction, slows the roller coaster down to a slow enough pace that it eventually stops.
Kinetic Energy.
the two forces are friction and gravity
Kinetic or centrifugal, depening what phase you are on.
