why goft ball is not smooth?

Answer 1

Its so that if your swing is off target by one or two angstroms then your ball can go whirling off into the woods, never to be seen again.

Answer 2

Air travels around the ball further before separating, creating a smaller wake and much less drag while the spinning motion warps the airflow to generate lift as shown in the flow pattern.

Surprisingly, the phenomenon described above gives a dimpled golf ball only about half the drag of a smooth one. A perfectly smooth golf ball with no dimples would travel about 130 yards when hit with a driver by a good player. On the other hand, a ball with well-designed dimples, struck the same way, will travel about 290 yards.

Answer 3

A golfball has "dimples".
It has to do with aerodynamics.
They allow golfers to hit balls much higher and farther than when
golfballs had NO dimples.
The dimples are there to reduce the aerodynamic drag, that would be acting on the ball if it were entirely smooth.
A smooth ball when struck by a driver, would probably carry about 110 yards in the air where a dimpled golf ball is going to carry 250 yards. So that's a huge difference.

Answer 4

Most balls on sale today have about 300 to 450 dimples. There were a few balls having over 500 dimples before. The record holder was a ball with 1,070 dimples -- 414 larger ones (in four different sizes) and 656 pinhead-sized ones. All brands of balls, except one, have even-numbered dimples. The only odd-numbered ball on market is a ball with 333 dimples.

Officially sanctioned balls are designed to be as symmetrical as possible. This symmetry is the result of a dispute that stemmed from the Polara, a ball sold in the late 1970s that had six rows of normal dimples on its equator but very shallow dimples elsewhere. This asymmetrical design helped the ball self-adjust its spin-axis during the flight. The USGA refused to sanction it for tournament play and, in 1981, changed the rules to ban aerodynamic asymmetrical balls. Polara's producer sued the USGA and the association paid US$1.375 million in a 1985 out-of-court settlement.

The United States Patent and Trademark Office's patent database is a good source of past dimple designs. Most designs are based on Platonic solids such as icosahedron.

Answer 5

Inventors discovered that a smooth golf ball did not fly as far because it created a pressure zone immediately behind it that slowed it down. The dimples prevent (or at least diminish) this pressure difference, allowing the ball to travel farther.

Answer 6

if it was smooth it would spin out of control. little air pockets build up on each dimple and that helps the ball go straight. i don't play goft though.

Answer 7

The dimples on a golf ball are not there by accident. They are scientificly engineered to preform diffrent tasks, helping aerodynamics, generating lift, reducing drag, helping reduce slices. Some balls will go further, some will have more stability, with more control... Millions if not billions of dollars are put into these little dimpled balls

Answer 8

The dimples create vortices that help it fly straighter. Basically it creates a film of air close around it that keeps it from being disturbed by other air flowing past.

Smoother balls fly less well and move in random directions.

Answer 9

Short answer: So it will travel farther when it is hit with a golf club.

Answer 10

it has divets so that a boundary layer can build up and it can incur lift. this allows you to curve the ball using spin.
