Item RG028004: After a drummer hits a drum once, the energy of the drum will decrease because the sound will transfer energy away from the drum.

A drummer ends a song by hitting a drum with a stick. Hitting the drum causes the drum to vibrate and produce sound.

What will happen to the energy of the drum after the drummer hits it once but does not hit it again?

  1. The energy of the drum will increase because energy is created as the drum vibrates.
  2. The energy of the drum will decrease because its energy will be destroyed by the sound.
  3. The energy of the drum will decrease because the sound will transfer energy away from the drum.
  4. The energy of the drum will not change because the energy that the drum gained from being hit does not leave the drum.
