# Inelastic Collisions

Inelastic collisions represent a fundamental concept in physics, pivotal to understanding the conservation of momentum and kinetic energy within a closed system. Unlike elastic collisions where kinetic energy remains constant, inelastic collisions involve a loss of kinetic energy due to deformation or other forms of energy transfer, resulting in the objects sticking together or undergoing structural changes. This phenomenon finds application across various fields, from analyzing traffic accidents to studying celestial bodies' interactions. Understanding the dynamics of inelastic collisions provides insights into the behavior of matter under different conditions and contributes to advancements in engineering, astrophysics, and material science.
