Golf balls are unlike many other balls that are used in sports. They are small and have a firm rigid body. Despite the hard exterior, golf balls are surprisingly bouncy. There are many factors that lead to this bounce including shape, construction, and materials. Although there are several styles of golf balls, all golf balls bounce.
All golf balls contain several materials. Surlyn is a popular material for the outside of golf balls. This material is quite hard and is very cheap. The inside of golf balls is typically constructed with resin-type materials or rubber. Also, some golf balls may have weights in the middle to increase weight. The materials that are used in golf balls work together to create the signature bounce of a golf ball.
The shape of a golf ball is integral to it's bounce. Golf balls are spherical in shape which allows them to easily bounce straight off the ground, unlike odd shaped footballs.
Golf balls differ in the hardness of their shell. This hardness depends on factors such as shell material and design of ball. Harder balls tend to bounce better than their softer counterparts.
Newer golf ball designs all include a spherical shaped object inside the shell of the golf ball. Older designs used materials such as goose feathers which were uneven in shape.
A few of the popular designs include wrapping rubber thread around the core until it forms a ball, one piece ball construction that uses a round core wrapped in the shell, and multilayer construction.
Multilayer construction includes many spherical shaped parts that are built on top of each other. The spherical shape of golf ball contents helps create bounce.
When force is exerted on the golf ball, it moves in a particular direction. When it hits a surface, the force of physics causes it to move in the opposite direction.
