Question

Any collision that produces a sound is what type of collision?

1) elastic collision
2) inelastic collision
3) perfectly elastic collision
4) partially elastic collision

Answer 1

A collision that produces a sound is inelastic because some of the kinetic energy is transformed into sound energy, indicating that kinetic energy is not conserved in the collision.

Step-by-step explanation:

Any collision that produces a sound is an indication that some of the kinetic energy has been converted into sound energy, which means it is not conserved in the form of kinetic energy. Therefore, such a collision would be classified as an inelastic collision. In a purely elastic collision, all of the kinetic energy is conserved and remains as kinetic energy after the impact. However, in an inelastic collision, some of the kinetic energy is transformed into other forms of energy, such as sound, heat, or deformation energy. The most extreme form of an inelastic collision is a perfectly inelastic collision where the objects stick together and move with a common velocity after the collision, further reducing the internal kinetic energy.
