Why do golf balls have dimples?

I have long wondered why golf balls have those small dimples on their surfaces. I understand that every aspect of their design serves a purpose, but why the dimples? Do they truly make a difference?

I have heard a few opinions, ranging from enhancing aerodynamics to boosting distance, but I would like to receive more concrete answers and a better understanding of how these dimples affect the performance of golf balls. Is there anyone here who can educate me on this subject?

Dimples on a golf ball form a thin, turbulent boundary layer of air that adheres to the ball’s surface. This permits the smoothly moving air to follow the ball’s surface a bit further around the backside of the ball, reducing the size of the wake. A dimpled ball has approximately half the drag of a smooth ball.

Yes, the Mythbusters even aired an episode about it, where they covered a car in golf-ball-like dimples, which dramatically improved fuel efficiency.

The dimples on golf balls are there to significantly improve their aerodynamic performance. As a golf enthusiast myself, I’ve learned that these dimples create turbulence in the airflow around the ball, which reduces drag and allows it to fly farther and more accurately. Without dimples, the ball would experience more air resistance and have a much shorter flight distance. The dimples essentially help the ball stay in the air longer and maintain a more stable flight path by managing the airflow more efficiently. This design is a result of extensive research into aerodynamics, and it’s why modern golf balls have such distinctive dimples.

When the ball has a lot of backspin while flying in the air, the dimples provide lift.

Thanks for the detailed explanation! I’ve always wondered why golf balls have dimples, and your explanation makes it much clearer. It’s fascinating how something as simple as dimples can have such a big impact on performance. Understanding the aerodynamics behind it gives me a new appreciation for the design. Thanks for sharing your knowledge!
