Energy transfers
• from the piano keys to Kiara's fingers
Energy transfers from the piano pedals to the piano keys
Energy transfers from the air to Kiara's fingers
Energy transfers from Kiara's fingers to the piano keys.
When Kiara plays the piano, kinetic energy transfers from her fingers to the piano keys.
When Kiara plays the piano, kinetic energy transfers from her fingers to the piano keys. How does this happen? When Kiara presses down on a piano key with her finger, her muscles generate the force needed to push the key down. This mechanical force is converted into kinetic energy, which is the energy of motion. As Kiara's finger moves downward, the kinetic energy is transferred from her finger to the key, causing the key to move and produce sound.
So, to summarize, the kinetic energy transfer occurs as follows:
1. Kiara's muscles generate a mechanical force.
2. The mechanical force is converted into kinetic energy as her finger moves.
3. The kinetic energy is then transferred from her finger to the piano key, causing it to move and produce sound.
