# Crash and Sound Waves.

1. Apr 1, 2009

Greetings!
Once again I don't know where to classify this tread... sorry.
My Question is the following:
Let's say we have a ball of mass, m. Let the mass be a steal ball for example.
We throw the ball at the floor. The impact that follows surely is a non-conservative impact.
(I hope I said this one correctly... the "non-conservaty" means that some energy is lost)
I was wondering...
Do sound waves have energy? Or there are themselfs energy?
And if they do/are, then could we say that some part of the energy that is lost during the impact is turned to sound wave?
That's why we hear the "bam" ? :P
