Elastic Collisions
Elastic collisions are fundamental to understanding the dynamics of particles and objects in physics. In these collisions, kinetic energy is conserved, meaning the total energy of the system remains constant before and after the collision. Unlike inelastic collisions where kinetic energy is not conserved, elastic collisions involve no loss of energy due to deformation or other factors. This concept plays a crucial role in various fields such as mechanics, astrophysics, and engineering, offering insights into the behavior of particles ranging from subatomic particles to celestial bodies. Understanding elastic collisions is essential for predicting and analyzing the motion of objects in a wide array of contexts.
