Dictionary writer “suret035” has researched why golf balls are rough. Here you go.
Have you ever thought? Why is the surface of the golf ball rough? I’ve been thinking about it since last night, I researched it first thing in the morning, I learned and had a wonderful enlightenment. Let’s always be together:
The first golf balls had a smooth surface, but over time golfers noticed something interesting. Old and worn balls travel significantly farther. That’s when they started to crush and scratch the balls. Apparently, while the flat ball was moving through the air, its surface was surrounded by the resisting air. The split air was reunited behind the ball. The better an object breaks through the air flow and then allows it to merge, the more aerodynamic it is. The air vortices that form behind the ball at high speeds prevent the air flow from reconnecting behind the ball. This slows down the speed of the ball as it acts as a brake.
In the dimpled ball, small local vortices occur simultaneously all over the ball surface, which is uneven due to the dimples on it. These vortices were in the form of a sphere that surrounded the main air flow. Therefore, the dimpled ball was less exposed to air resistance. The air resistance of a ball with a flat surface is twice the air resistance of a ball with dimples.
Note: I have neither played golf nor driven a VW Golf. We, as a family, are fond of polo sports. Just kidding, but we have a 2006 model polo, we ride as a family, thank God we fit in well. If we find such a green golf course, we can barbecue and have a picnic. If there is a ball or something, maybe we will fight for a penalty at most. I watched the science thing in two minutes on NTV this morning, so I thought I’d write it in the dictionary so that we could be of service to the science channel. Fringe is nice but watch it.
