Question

1. Describe the following energy transformations for the following scenario:

A student plays piano in music class.

Answer 1

In music class, when a student plays the piano, kinetic energy is transformed into sound energy, and the potential energy of the piano strings is transformed into sound energy.

Step-by-step explanation:

When a student plays the piano in music class, there are two main energy transformations that occur:

1. Kinetic energy is being transformed into sound energy. As the student presses the piano keys, their finger movements generate kinetic energy, which is then transformed into sound energy as the keys strike the piano strings and produce musical notes.
2. The potential energy of the piano strings is being transformed into sound energy. When the student presses a piano key, it lifts a small hammer that strikes the corresponding string. The potential energy stored in the stretched strings is then transformed into sound energy as they vibrate and produce musical notes.

So, in summary, the energy transformations in this scenario involve kinetic energy being transformed into sound energy and potential energy of the piano strings being transformed into sound energy.
