My is there sound in this world whenever two (or more) things collide with each other?

Examples

  • When two cars collide
  • When something with enough mass falls from a height
  • When small drops of water fall into the any water container

There are so many things associated with a collision; why is Sound one of them?

This question is related to Earth’s atmosphere only, not vacuum.

This question is for sound related to collisions only. No vibrations.

when two cars collide, their bodywork very quickly crumples. the quick crumple can be though of in the same way that a drum head moves when struck with a mallet. the air near the drum head gets pushed and pulled by its motion and so does the air near the body panels of a pair of colliding cars. therefore, both of these things radiate sound through the air for the same reason.
