HELP ive got a HUGE science taske about rollercoasters and its really hard!
Gravity and Friction
Stop Height is the maximum height an object can reach without rolling backward. On a roller coaster, stop height is set by the height of the first hill. No subsequent points can be higher than this height. Friction and air resistance take energy away from the coaster and therefore reduce the stop height.
Brakes, either using friction or magnets, are used to slow down or stop the train usally at the end of a roller coaster ride.
Friction and Drag (air resistance)
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.
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.
It provides undesired slowing of the coaster on its path but it is essential for the brakes to stop it at the station.
A roller coaster or pendulum eventually comes to a stop due to energy loss from friction and air resistance. As the system moves, kinetic energy is converted into thermal energy through friction between surfaces and air drag, which dissipates energy. Additionally, the force of gravity acting on the pendulum or roller coaster reduces its potential energy as it swings or descends. Over time, these energy losses result in a gradual decrease in motion until it comes to a stop.
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.
they have a braking system
