Identify which best describes the energy used to pluck guitar strings to make sound.

The energy used to pluck guitar strings to make sound is called the kinetic energy. After the action has been done, this energy will move to the strings at a constant speed creating vibrations that generate the sounds. The loudness of the sound will depend on the pressure put unto the strings.

The correct answer is: Mechanical Energy

Explanation:

As the guitar strings are plunked, the potential energy stored in the strings has an ability to make them vibrate. When the strings are vibrating, that potential energy is actually converted to the kinetic energy. Hence, the whole phenomena contains both the kinetic energy and the potential energy. The sum of kinetic energy and the potential energy is called Mechanical energy. Therefore, the correct answer is Mechanical Energy.
