Why is a Golf Ball Heavier than a Tennis ball

A golf ball is typically heavier than a tennis ball because it is made from denser materials and has a smaller size.

Golf balls are designed to have a solid core made of rubber or synthetic materials, which is then covered by a series of layers of materials like plastic or rubber. The outer layer, also known as the cover, is typically made of a type of plastic called Surlyn or a softer, more expensive material called urethane. The combination of these materials creates a golf ball that is both durable and responsive to a golfer’s swing.

On the other hand, tennis balls are made of a hollow rubber core covered in a layer of felt. The felt layer provides some protection to the ball and helps to slow it down when it is hit, but it is not as dense or heavy as the materials used in a golf ball.

Additionally, golf balls are designed to be smaller in diameter than tennis balls. According to the rules of golf, a standard golf ball must have a diameter of at least 1.68 inches, while a tennis ball has a diameter of approximately 2.7 inches. The smaller size of a golf ball means that it contains less air and takes up less space, which contributes to its greater weight compared to a tennis ball.

Another factor that contributes to the weight difference between golf balls and tennis balls is the intended use of each ball. Golf balls are designed to be hit long distances with a high degree of accuracy, whereas tennis balls are designed to be hit back and forth over a net with a relatively low degree of force.

As a result, golf balls need to be heavier and more durable to withstand the high impact forces generated by golf club swings. In contrast, tennis balls need to be lightweight and soft enough to be hit repeatedly without causing injury to players.

Another aspect that affects the weight of a golf ball is the number of dimples on its surface. Dimples are small indentations on the surface of the golf ball that reduce drag and improve the ball’s aerodynamics, allowing it to travel further and with more accuracy. The number of dimples on a golf ball can range from around 300 to over 500, with the more dimples generally indicating a more advanced ball design. The presence of dimples does not significantly affect the weight of the golf ball, but it does contribute to its overall performance.

In conclusion, the weight difference between golf balls and tennis balls can be attributed to various factors, such as the materials used, size, intended use, and design features such as the presence of dimples. Overall, golf balls are heavier than tennis balls because they are designed for a different purpose and need to be able to withstand high impact forces while maintaining accuracy and distance
