Energy: Forms, Transformation, Transfer, and Conservation
Item RG040003: When a tuning fork slows down and eventually stops vibrating, some of the energy is transferred to the surrounding air.
A repairman uses a tuning fork, like the one shown below, to tune a piano. He hits the tuning fork against the edge of a table. The tuning fork begins to vibrate. The vibrating tuning fork makes a specific sound, and the repairman adjusts the piano until it makes the same sound when played. After a while, the tuning fork stops vibrating, and the sound stops.
What happens to the energy of the tuning fork as the vibrations of the tuning fork slow down and eventually stop?
- Some of the energy is destroyed by the sound.
- Some of the energy is transferred to the surrounding air.
- Nothing happens to the energy because sound is not related to energy.
- The energy runs out because the force that was given to the tuning fork runs out.
