Golf balls
Golf balls are small spherical balls hit by the golfer
on a golf course. There are several brands of golf balls including Titleist
and Nike. These companies often pay celebrity golfers to endorse their
equipment.
Golf balls are divided into two categories: recreational and advanced.
Recreational golf balls are marketed toward the weekend golfer and are
made of only two layers. Advanced balls are made of multiple layers
and have a soft cover and a firm core.
Recreational golfers always face the challenge of keeping their golf
balls. In order to help prevent golfers from losing their golf balls,
manufacturers place their name and a number on the ball. According to
USGA rules if an incorrect ball is struck by a golfer it can cost the
golfer a penalty.
