The chemical composition of the ball establishes elasticity, determines the ball’s ability to hold energy when deformed, and subsequently affects bounce. With increased elasticity, more energy is retained in the rubber and is recovered when turned on. Different rubber materials retain different amounts of energy – all rubber is not created equal. Therefore, the bounce of a tennis ball is largely controlled by the molecular structure of the rubber.Read more: why are eyelashes longer | Top Q&AA and although our modern tennis balls are always made of rubber, the bright yellow fluff is not always a popular look.
