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 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?
d
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 the main energy transfers that happen as a roller coaster cart travels along the track fromthe start of the ride to the end?
Basically the main energy transfers in a Roller Coasters are, Gravitational Potential Energy (PE), Kinetic Energy (KE) and some energy is lost through Heat and Sound.
What is the usefull and wasted energy in a hair dryer?
Sound energy from the hair dryer is wasted.
Why is heat the most common form of wasted energy?
Heat energy is the most wasted form of energy.
What energy is wasted by a fan?
sound
What energy is wasted by a microwave?
Sound
Why is sound energy wasted when a kettle is heated?
when th kettle is heating up it making a boiling sound throught the process. This is sounded energy that is not being used hence wasted sound energy
What energy is wasted froma washing machine?
Heat energy and Sound energy
What type of energy is wasted when energy is converted?
thermal, light and sound
