Question

a guitarist stretches and releases a string while playing a guitar. which statement about the energy of the string is correct? select all that apply
the kinetic energy of the string converts into sound energy.
the string stores energy in the form of potential energy.
the string stores energy in the form of kinetic energy.
potential energy is converted into kinetic energy when the string is released.
the kinetic energy of the string converts into electrical energy.
kinetic energy is converted into potential energy when the string is released.

Explanation:

• When the string is stretched, it stores energy in the form of potential energy (elastic potential energy).
• When released, the potential energy is converted into kinetic energy (as the string moves).
• As the string vibrates (has kinetic energy), it converts some of that kinetic energy into sound energy (which is how we hear the guitar sound).

Answer:

• The kinetic energy of the string converts into sound energy.
• The string stores energy in the form of potential energy.
• Potential energy is converted into kinetic energy when the string is released.
