What are some examples of energy transformations, particularly in the context of roller coasters?
Understand the Problem
The question presents information about energy transformations, particularly in the context of roller coasters and various conversions of energy types. It includes equations for potential and kinetic energy as well as examples of energy transformations in different contexts.
Answer
Potential energy to kinetic energy in roller coasters.
In roller coasters, potential energy transforms into kinetic energy as the cars descend the first hill. Additionally, some kinetic energy changes back into potential energy as the coaster ascends subsequent hills. Other transformations include kinetic energy to thermal and sound due to friction and noise.
Answer for screen readers
In roller coasters, potential energy transforms into kinetic energy as the cars descend the first hill. Additionally, some kinetic energy changes back into potential energy as the coaster ascends subsequent hills. Other transformations include kinetic energy to thermal and sound due to friction and noise.
More Information
Roller coasters vividly demonstrate the principle of energy conservation: as they go through hills and loops, energy shifts between potential and kinetic forms. Friction also turns some energy into heat and sound.
Tips
Mistaking total energy loss for transformation. Remember, some energy converts into sound and heat, not lost.
