Roller Coasters waste energy through sound and heat. The wheels on the cart and the metal tracks grind together to make a fricional pull. this causes the screeching sound when the cart stops, and the heat of the track.
What else can I help you with?
What are energy conversions on a roller coaster?
electrical energy to sound, mechanical energy
When rolling downhill a roller coaster's potential energy is converted into a kinetic energy b thermal energy c sound energy d all of the above?

Is gravatational energy kinetic or potential energy?
Gravatational and Potential Energys are the same, they simply both have the potential to fall (its higher up) and Kintic Energy is was is created when for example a roller coaster moves?! I has Kinetic Energy and some is lost throughout sound and heat as thats is another type pf energy that is created when a roller coaster moves.
Why do roller coasters end lower than where they start?
Since the top of the first hill is the highest point on the track, it's also the point at which the roller coaster's gravitational potential energy is greatest. As the roller coaster passes over the top of the first hill, its total energy is greatest. Most of that total energy is gravitational potential energy but a small amount is kinetic energy, the energy of motion. From that point on, the roller coaster does two things with its energy. First, it begins to transform that energy from one form to another--from gravitational potential energy to kinetic energy and from kinetic energy to gravitational potential energy, back and forth. Second, it begins to transfer some of its energy to its environment, mostly in the form of heat and sound. Each time the roller coaster goes downhill, its gravitational potential energy decreases and its kinetic energy increases. Each time the roller coaster goes uphill, its kinetic energy decreases and its gravitational potential energy increases. But each transfer of energy isn't complete because some of the energy is lost to heat and sound. Because of this lost energy, the roller coaster can't return to its original height after coasting downhill. That's why each successive hill must be lower than the previous hill. Eventually the roller coaster has lost so much of its original total energy that the ride must end. With so little total energy left, the roller coaster can't have much gravitational potential energy and must be much lower than the top of the first hill.
What are 5 energy conversions in a roller coaster?
Potential energy to kinetic energy: at the top of a hill, the coaster has high potential energy which is converted to kinetic energy as it speeds down the hill. Kinetic energy to potential energy: as the coaster climbs up a hill, its kinetic energy decreases and is converted back to potential energy. Mechanical energy to thermal energy: friction between the coaster and the track converts mechanical energy into thermal energy, causing the coaster and track to heat up. Electrical energy to kinetic energy: in a launched coaster, electrical energy is converted to kinetic energy as the coaster accelerates along the track. Potential energy to sound energy: when the coaster goes over bumps or loops, potential energy is converted to sound energy as the coaster vibrates and creates noise.
What type of energy is wasted when energy is converted?
thermal, light and sound
If a roller coaster car is pulled by a chain at the beginning of the ride what kind of energy is present at this point?
The motor that drives the chain is being fuelled with electrical energy, which it converts into kinetic energy to move the chain. The chain supplies the rollercoaster carriage with kinetic energy and (hence why its harder to pull something up a slope) gravitational-potential energy. When the chain releases the carriage, and it speeds down the track, it converts its GPE into kinetic energy and thermal/sound wastes.
What is the wasted energy from a car engine?
heat and sound
How much energy is wasted as sound?
The amount of energy wasted as sound depends on the specific situation and source of sound. In general, energy is lost when vibrations created by an object or source are converted into sound waves. This energy loss can vary, but typically only a small percentage of the original energy is converted into audible sound.
What happens when a roller coaster suddenly goes downhill?
the car looses potentional force and gains kinectic and sound :)
Why is sound energy wasted when a kettle is heated?
Sound energy is produced when the water inside the kettle is heated because the boiling water releases water molecules that collide with each other, creating vibrations in the air that we hear as sound. This sound energy is considered wasted because it does not contribute to the main purpose of the kettle, which is to heat the water.
Where on a roller coaster does energy transform?
As it starts to climb the lift hill, the electrical energy builds potential energy. On its way down the first drop, the cars gain kinetic energy (energy of motion) and lose potential energy (stored energy). When it goes up the next hill, the potential energy increases and kinetic decreases, evident in the cars slowing down. Potential is greatest at the top of the highest hill. Along the way, more energy is lost in friction and sound energy.
