Why do golf balls have dimples?
The dimples on golf balls influence its speed and trajectory. It is a fact: without the dimples, balls only fly 50% of the distance they fly with the dimples. But accuracy is key here: even the smallest differences from the standard size (the dimples are about 0.010 in deep) will change its characteristics. By the way, most golf balls have from 300 to 500 dimples.
