Question
Direction : Identify the energy common in each of the examples given.
Music from a piano , girl shouting , speakers playing
- Thermal
- Chemical
- Mechanical
- Sound
Hint:
Sound
The correct answer is: Sound
Sound energy is the result when a force, either sound or pressure, makes an object or substance vibrate. That energy moves through the substance in waves. Those sound are called Kinetic mechanical energy.
Music from a piano, a girl shouting and speakers playing all create vibrations which produce sound.

Which type of energy is produced when the handle of a pencil sharpener turns?
¶Potential and kinetic energy sources from which mechanical energy is generated by converting them into power. Turbines powered by steam, water, wind, gas, or liquid fuels are a few examples of this.
¶Before being employed as power, machines were frequently used to convert various energy sources. We can use mechanical energy any way we want or need it to function once it has been altered in a specific way. E.g., A tool that works by using mechanical energy is a hammer. A hammer's ability to exert force on a nail to move it is made possible by the mechanical energy it possesses. The hammer can function on the nail because it possesses mechanical energy (kinetic energy). Work-enabling energy is known as mechanical energy.
