A non-central elastic collision is a type of collision in which the kinetic energy of the system is conserved, and the objects involved do not collide head-on. Instead, the collision occurs at an angle, resulting in a change in the direction of motion for both objects while conserving their total kinetic energy. This type of collision is more complex than a central elastic collision, as it involves both linear and angular momentum conservation principles. **
