Elastic collision is an important concept in physics that describes a type of collision where the total kinetic energy of two or more objects involved in the collision is conserved. In simpler terms, an elastic collision is a collision where objects bounce off each other without any loss of energy. There are several synonyms for the term elastic collision, such as perfectly elastic collision, all-or-nothing collision, and reversible collision. These terms are used interchangeably to describe the same type of collision. Elastic collisions are widely studied in physics and are crucial for understanding the behavior of particles and molecules in various fields, including engineering, chemistry, and material science.
