Inelastic Collision:An inelastic collision is a type of collision where kinetic energy is not conserved before and after impact. Some energy is lost, usually in the form of heat or deformation.
Coefficient of Restitution: The coefficient of restitution measures how bouncy a collision is by comparing the relative velocities before and after impact.
Conservation Laws:Conservation laws are fundamental principles that state certain quantities (such as momentum or energy) remain constant in isolated systems, even if their forms may change.
