An elastic collision is a type of collision between two objects in which both kinetic energy and momentum are conserved. In this scenario, when two bodies collide, they don’t experience any loss of kinetic energy due to deformation, heat, or sound production. Instead, the total kinetic energy of the system before the collision remains equal to the total kinetic energy after the collision. During an elastic collision, both momentum and kinetic energy are preserved because the forces involved are conservative and no external forces, such as friction or deformation, act on the system to dissipate energy. These collisions are idealized scenarios often studied in physics to understand the principles of conservation of energy and momentum. In real-world situations, perfectly elastic collisions are rare as some energy is usually dissipated due to factors like deformation or friction. However, in certain atomic or subatomic interactions, particles can undergo nearly elastic collisions due to the absence of significant external forces, allowing conservation of kinetic energy and momentum to a high degree of accuracy.
