Differentiate the old and new volleyball?

The old volleyball, typically made from leather, was heavier and had a less consistent bounce, making it more challenging to control. In contrast, the new volleyball is often constructed from synthetic materials that provide better durability, a lighter weight, and improved aerodynamic properties. Additionally, modern volleyballs have enhanced seam designs that reduce the chances of injury and improve grip. These advancements have led to more dynamic gameplay and greater player performance.
