![]() ![]() ![]() Dimples help the fluid to “stick” to the golf ball farther around the diameter, which increases drag. The result can also be explained by fluid dynamics because of the way the dimples change fluid flow around the object. Surface area partially explains the strong performance of Titleist because the specific design of the Titleist golf ball has a smaller surface area than the competitors, which creates a lower overall drag force. This result can be explained by fluid dynamics and surface area. The Top-Flite was even farther from Titleist than Callaway was. The runner-up to Titleist was Callaway, behind by. The Titleist golf ball proved superior by falling faster than its opponents by an average margin of just over a second. This was repeated three times for each ball. As it reached the bottom, the timer was stopped and the results were recorded. One of the chosen dimple patterns was dropped into the tube and timed as it fell. ![]() I also used a ladder, pipe cap, stopwatch and retrieval apparatus.Īfter the tube was sealed on one end with the pipe cap, filled with water, and secured to an upright ladder, the experiment was ready to be conducted. The experiment was set up using a clear plastic tube eight feet in length and two inches in diameter. ![]() My independent variable included three dimple patterns: Top-Flite D2 Feel, Callaway Chrome Soft, and Titleist ProV1. In this experiment, effects of lift and thrust were eliminated, and only drag and gravity are in play. However, water is nearly a thousand times more dense, which magnified my results and made the experiment more measurable. Water works to test ball flight because believe it or not, air is also a fluid. I designed my experiment to test which golf ball would travel fastest, and by association further, through a liquid. The overall force of lift and thrust must overcome the overall force of drag and gravity for an object to become airborne. It is because of gravity that things feel heavy. Gravity is the downward force on an object. Drag is the friction force acting on the golf ball, generated by the airflow over the surface of the ball. Thrust is the force that pushes an object through the air (in this case, a golf ball). Lift is the upward force on an object, acting against gravity. His four principles – lift, thrust, drag and gravity – are some of the most important ideas in our world today. George Cayley, the English pioneer of aerodynamics, developed four aerodynamic principles behind that 250-yard drive. There’s a surprising amount of science in the flight of a golf ball. Even though all of that energy is present, without those little dimples on the golf ball, my massive 250-yard drive is going to rapidly diminish into a poor 150-yard breakfast ball. There is so much energy behind a golf swing that the golf ball would completely shatter if it didn’t absorb some of it. When I step up to a golf ball and prepare to pound it 250 yards down the fairway, I never realized that upon impact, the golf ball is compressed up to one-fourth of its diameter. Why not conduct an experiment on three of my favorite golf balls to find out which one can be proven superior? What’s an interesting science project idea for an avid 13-year-old golfer? When I was assigned a large science presentation at my middle school, I cycled through several ideas before I realized that my golf game could actually benefit from the project! I’m always experimenting and looking for the perfect ball for my own game. Breaking it down for you, one dimple at a time ![]()
