Question

why sound produce when two metals are hit on each other!?​

Answer 1

because they are made of metals and matels have the ability to produce a sound when hitted

Answer 2

$\color{red}ANSWER$

When two objects/ metals collide and undergo a partially inelastic collision (so every one we experience in every-day life), they rebound to a certain degree, but kinetic energy is not conserved.

Thus, the energy of motion must be converted to another type of energy.

Thus, when two object collide,

the most common forms of energy that kinetic energy is converted to are sound energy and thermal energy.
