The bounce of a golf ball is explained by Newton's Third Law of Motion. Newton's Third Law of Motion states that for every action there is an equal and opposite reaction.
When two objects collide, the direction of the force on one object is also applied in the opposite direction on the second object. Thus, when a golf ball falls on the ground, the greater upward force overcomes the ball's mass, careening it back into the air. The higher the acceleration of the ball, the greater the opposing force. For this reason, the harder the ball falls on the ground, the higher it bounces back.
Golf balls are unlike many other balls that are used in sports. They are small and have a firm, rigid body. Despite their hard exterior, they are surprisingly bouncy. There are many factors that lead to the bounce, including shape, construction and material.
Golf balls contain several materials. Surlyn is a popular material for the outside of golf balls. This material is quite hard. The inside of the ball is typically constructed with resin-type materials or rubber. Some golf balls have added weights in the middle for better bounces. The materials used in golf balls work together to create the signature bounce of the ball.
The shape of a golf ball is integral to its bounce. Golf balls are spherical in shape, which allows them to easily bounce straight off the ground.
Golf balls differ in the hardness of their shell. The hardness depends on factors such as shell material and design of the ball. Harder balls tend to bounce better than their softer counterparts.
