The correct answer is: Energy transfers from Kiara’s fingers to the piano keys.
The correct answer is: Energy transfers from Kiara’s fingers to the piano keys.
To understand how kinetic energy transfers from one object to another when Kiara plays the piano, we need to understand what kinetic energy is and how it is transferred.
Kinetic energy is the energy an object possesses due to its motion. When Kiara plays the piano, she moves her fingers rapidly, creating motion. As her fingers strike the piano keys, the kinetic energy in her fingers is transferred to the piano keys.
This transfer of energy occurs because when Kiara's fingers make contact with the piano keys, the kinetic energy in her fingers is transferred to the keys through the collision. The energy is transferred in the form of vibrations, causing the piano strings to vibrate and produce sound.
Therefore, when Kiara plays the piano, the kinetic energy transfers from her fingers to the piano keys.
